Understanding Implantation Bleeding

Implantation bleeding is a pink or brown vaginal discharge that generally occurs six to 12 days after ovulation and fertilization. Most women do not experience implantation bleeding, and doctors suggest that just 1/3 pregnant women will report any such discharge at or around the time they find out they are pregnant. The discharge occurs when the fertilized egg implants in the uterus, which is why it is referred to as implantation bleeding.

Usually, you can test for pregnancy and get an accurate result right around the time that you experience implantation bleeding, though your hcg levels may not be high enough to register a positive until 2 or 3 days after implantation.


Many women get scared when they see implantation bleeding or assume that they must not be pregnant because it looks like period blood. Cramping, backache, or increased bleeding does not usually accompany implantation bleeding. For most women, implantation bleeding is simply a bit of brown or pink colored discharge mixed in with a clear discharge.


If you have already confirmed your pregnancy and it is more than 10 days since fertilization, you probably will not see the implantation bleeding, so if you see blood you should call your doctor and follow his or her instructions carefully as you could be experiencing a miscarriage.

If you do believe you are experiencing implantation bleeding, you can go ahead and test for pregnancy like you normally would. Many women assume that the blood will affect the results of a standard home pregnancy test, but this is not the case. If there is hCG present in your urine, a home pregnancy test may show a positive result.

If there is no hCG present in the urine, it will come back negative. Because your urine and the bloody discharge come from different parts of the body, the small amount of implantation bleeding will not skew the results of your test. If for some reason the test is negative but you do not continue to bleed as you would with your period, test in 2-3 days to give you body time to produce a high enough level of hCG to be picked up by your test.

If you still have not started your period within a week and you do not get a positive test result, you may want to contact your doctor and ask her how you should proceed as he or she may want you to have a blood test done to determine if you are pregnant.

Luckily, because most women do not experience implantation bleeding, there is no need to concern yourself with this. If you are worried that you did not experience this bleeding because your friend did, don’t assume that there is something wrong with your pregnancy. Whether or not a woman experiences implantation bleeding doesn’t seem to affect the outcome or overall health of a pregnancy, so as long as the bleeding is just a little bit or you don’t bleed at all, implantation bleeding need not be a concern to you!

    Hi I had my period on 12th December as normal. I am actively trying to conceive. My period was due 8th January. From 1st January to 5th I had very light brown spotting, not enough to use a tampon or a pad but it was still there. On the day that my period was due I had a negative pregnancy test. My period came on 9th January but is different to every month- it is unpredictable light and heavy on and off with a large amount of stretchy clear discharge (similar to when I am ovulating). I have done another pregnancy test today (11th January) with a negative result. If anyone has any ideas what this could be it would really help. Thanks.

    Hi! My husband and I have been trying to get pregnant for over a year now and we’ve just recently started using opk’s to help. On my two most fertile days (confirmed with both positive opk’s) we had sex. After the second day I bled immediately after sex. I shrugged it off as just being a little rough. Since then, I’ve been spotting off and on for almost two weeks. It’s always bright red and I get very mild cramps. I’ve been having dizzy spells, weight gain, my boobs are more tender than usual, been gassy, and I’ve been more thirsty than usual. I’ve taken a pregnancy test a few days earlier than I know I should (about 4 days before my period is due) and it was negative. I’m so confused. I never spot in between periods and I’ve never experienced anything like this before. I’m always able to predict my cycles and I’m always regular. Any ideas on what it could be?

  • dour

  • catwomen

    ok, omg if someone would know about these please reply: So I was on BC for 10 years, back in June 2014 I decided to stop the pill, it began with an irregular periods up to October! I would get 35-40 cycle coming November I have finally stayed on the 32/33 day cycle considered normal! so it is February 2015 3 months of completely normal I been trying so hard for a baby_ I finished my last period Jan18,2015 had sex Jan 21st 3 days after, Jan 24/25 and 27 on the 27th I had spotting the next morning when I went to pee just when I wiped and lil cramps throughout the day, coming the next day again spotting then NOTHING my next period should be Feb 15,2015 in a couple of days could I been experiencing implantation bleeding? could I’ve had ovulated 3 days after my finished period? someone please please explain I will test if I do not get my period, But I have been drinking and living my normal life just a lil concerned 🙁

  • Depends on how long you bled for. The first day of bleeding is where you count from. For a 33 day cycle, you would have ovulated around day 18 of your cycle. If you had sex around then, then yes, you could be pregnant.

  • chinita

    I haven’t had my period in 2 months and yesterday I experienced the light blood but I’ve taken pregnancy tests and all say I’m not pregnant… I’m confused

  • Have you been to see a doctor about this? It could be that you have a hormone imbalance that is to blame for the missing period.

  • Nana

    Hey I haven’t had my period since October 4 2014 I took like 5 pregnancy test they all came back negative I been having ligh brown spotting just for one day I really don’t feel like I’m pregnant at all some time I feel dizzy or light headed moddy but that’s all can you please help me

  • There are many reasons your period can go missing in addition to pregnancy. A condition like PCOS can cause this as can menopause. You might want to go and visit your doctor to see if they can help you figure out what is going on.

  • Sam

    I just had my period about two weeks ago. And i had protected sex about a month ago. But now i’m having terrible cramps with brown spotting where I have to wear a panty liner. I’ve been spotting for about 3 days and then today i noticed a red flow when i peed. I also noticed some small tissue like substances in the toilet once i peed. I took a pregnancy test and it turned out negative. Did i test to early? I really hope I’m not pregnant because I’m to young. Do you know what this could be? I feel like sometimes i can be a hypochondriac and assume the worst so some feedback would be great!

  • What you could be experiencing is ovulation bleeding, which happens from time to time for some women. If you keep spotting a visit to your doctor to ease your mind might be in order.

  • Shantae270

    I want to know if I may be pregnant. My period is super weird. I have been having weird periods lately. I had unprotected sex in February this year, and my period was due March 7 2015. I spotted 3 days before it came on, but never fully came on. Now, after sex I spot. Been cramping a lil, like my period is coming on, but nothing. My breasts arent sore at all, but I have been feeling nauseous alot. Been craving spinach, and I got sick like I had a stomach virus or something. I don’t know what it could be, or if I am pregnant. Someone help me.

  • Have you taken a pregnancy test? And have you seen a doctor to make sure there is nothing, non-pregnancy related, going on with your system?

  • Saz

    I’m 2 days late for my period and I’m not cramping like mad, I’m also getting brown discharge my question is, should I be using tampons in case I am pregnant

  • A’s Smith

    Okay,, so I started my period yesterday to realize early this morning I have clear stretchy discharge mixed in it. An it was one pad worth all day an now it’s turned bright pink bleeding. Could I be pregnant no cramps like normal an my period is also a week early any ideas.

  • It shouldn’t be a problem.

  • You could have been having implantation bleeding. You could probably test now and get accurate results with a pregnancy test.

  • Lucy

    I had my first depo shit in July an that was my last shot I bleed for almost 3 weeks in august then after that I haven’t had anymore bleeding but in January I started spotting on an off for a week then it was gone now I’m spotting off an on again its only there when I wipe what could be going on an every pregnancy test is negative

  • It sounds like the depo really messed up your cycles. What did your doctor say about what you are experiencing?

  • Minniemouse22

    I started spotting on March 21 and match 22 I was suppose to get my period April 2 it’s now April 14 no period but I am having some spotting what does this mean

  • Have you taken a pregnancy test?

  • priya

    I hve seen spotting in both red and pink colour before 1 week of my period date .I hve taken pregnancy test but negative .Wat should i do

  • The earliest you will get a reliable result on a pregnancy tests is a day or two before your period is due to arrive. Test again when you are closer.

  • tiff

    Hello. I was just wondering if anyone could help me out. I’m 15 and I was suppose to have my peirod today but all that came was brown discharge but then when I pee I wipe and there is blood but nothing else when I don’t use the bathroom. I’m usually a heavy bleeder and I had sex every week since the end of April. My boobs hurt and I’m bloated but I don’t know if I’d be pregnant or not. I’m nervous that I might be but I don’t have the money for a test and I can’t tell my dad. Need some help Thanks.

  • Dione

    Hey just a question. Had period 2 weeks ago and 2 days ago I peed and when I wiped saw bright red wipe of blood. NotHing since and period is due in like 3 days. Implantation bleeding or something else??

  • Actually it would have been most likely ovulation bleeding, not implantation bleeding considering the timing.

  • Conner Gregory

    Me an my boyfriend had sex on the 26th of November during my ovulation period trying to conceive and two days ago I noticed a little bit of light pink blood with egg white mucas. It only happens when I wipe I put a pad on to track the bleeding and nothings on my pad but I still have blood when I wipe. I’ve also been increasingly nautious last night I had to pull over on the road to vomit and then I was fine I’ve also noticed I’m increasingly more constipated and certain foods or smells make me sick almost immidiatly. A friend of mine told me that bleeding this early means that my body is rejecting an egg is that true? And could I possibly be pregnant?

  • Tonya

    Ok so ever since I started getring a period, I have never missed one. Being a day or 2 late or early has happened. On the 7th of this month, my bf and I had unprotected sex and it was a day before I ovualted. I was suppose to start my period yesterday, the 22nd. But I haven’t. On Sunday, the 20th, I started feeling some mild cramping and when I would go to the bathroom, I would wipe blood from me. It would only be a little bit, but nothing would be on my pad. Its been that way since. I have some serious fatigue and my lower back hurts. The cramping feels like normal menstrul cramps, but I just dont understand why nothing is on my pad. I’ve never experienced anything like this before with my body, so I’m little scared

    Hi I’m new to this. 21 years old and have been on birth control since I was 18. My periods are always regular due to being on BC & I never miss a pill (at most maybe by a few hours). I always have unprotected sex with my partner but this month I started my “period” a week early. My periods are usually normal, heavy, normal, light lasting up to 4days. My “period” this month started exactly a week early and has been very light only using a panty liner. Started off light pink spotting now it is red blood. It is very light and does not bleed when I lay down. I am on day 9 of bleeding and now only seems to see blood when I wipe. I also feel very fatigue, dizzy sometimes, and occasional headaches/nausea. No regular symptoms as if I was having my actual period. Made an appt with my dr for the 5th but in the mean time I’ve been worried if possibly Prego or something may be wrong!! Any advice?

  • Sara

    Hi, did you ever figure out what was wrong? I have experienced this with the past three cycles.

  • Cinthia Miranda

    I’m curious to know. So I’ve had sex about 5-6 days ago and I’ve had some cramping here and there. Today I’m experiencing some light pink / brown blood. Can it be implantation bleeding? My period wasn’t due for another 6 days.

  • Brennda

    i was spotting 2 days after i missed my period and it went on and off then one day i bled like I normally would , Then it stopped. i peed clear and when wiped it was a little blood but not much, I only needed a panty liner and nothing more , would this be consider implantation bleeding ? It only lasted 3 days Help

  • I’m a little confused. Was this bleeding you are talking about when your period would normally be there or in the middle of your cycle? Implantation bleeding usually occurs 4 to 7 days before your period is due. http://www.babyhopes.com/articles/conception-implantation.html

    Sorry for TMI
    But I started bleeding 3rd December afternoon it was very light light red pinky blood.. that night it was watery with pink slime in it and on 4th it became darker red with tiny clots.. got back ache and stomach cramps on and off too 5th today it’s become a bit heavier but still not enough to fill a pad and blood clot when I wee. Still lower back pain and stomach cramps also dull ache in top of legs.. this is not like my normal period.. also was 16 days today since intercourse.. could this be implantation bleeding?
