How effective is taking birth control pills at preventing pregnancy?

If you use it properly, the pill is very effective. Some people aren’t perfect, which means that taking a pill is about 91% effective. That’s an alarming number, which means that about nine out of 100 people who take birth control pills get pregnant each year.

Assuming that you take all of your birth control pills exactly as prescribed, there is only a 1 in 1000 chance that you would become pregnant. This works out to a 0.1% chance of pregnancy. However, if you miss one or more of your birth control pills during the month, or if you take one late, you are more likely to become pregnant; your chances of becoming pregnant if you don’t follow the directions exactly rise to around 5%, or 1 in 20. Because of this, some women do indeed become pregnant while they are on birth control pills. If you haven’t taken your medication as prescribed, you may accidentally get pregnant.

Reasons for birth control pill failure

You may be using the wrong brand or type of pill.

Manufacturers can make birth control pills with various active ingredients, and some types of pills are more effective than others. Some birth control pills have a higher level of hormones than other pills, so they may be more effective at preventing pregnancy. If you’re taking a pill with low levels of hormones, it may not work as well. To ensure you’re getting the most effective pill possible, check the label to see what the manufacturer recommends. It would be best if you discussed the various brands available with your doctor.

Missing a day

If a person takes the pill daily, they will remain protected against pregnancy. If a person finds it challenging to take birth control pills every day and skip a day, other birth control methods may be more suitable. A doctor or gynecologist can help to advise about the different range of contraceptives.


Sometimes taking the birth control pill can upset your stomach and make you feel nauseous. If you vomit after taking the birth control pill, there is a chance that the pill did not fully dissolve. If this is the case, your birth control may end up failing you. You should take another pill if this happens to you and take your next pill as usual.

Early signs and symptoms of pregnancy

  • Unusual breast tenderness
  • Emotional highs and lows
  • Fatigue

Will taking birth control affect the accuracy of a home pregnancy test?

The hormones in your birth control pills won’t affect the outcome of a pregnancy test. they don’t contain the hormone that a pregnancy test detects, hCG, so you’ll never have to worry about your pills causing you to miss a positive or negative result. Now, if you don’t follow the instructions for using the pregnancy test, you could end up with an incorrect result.   

Is it dangerous if I take birth control pills while pregnant? 

If you are worried that you took the pill before knowing you were pregnant, talk to your doctor. There is no scientific proof taking contraceptive pills will cause you to have a baby that isn’t healthy, nor will it increase your risk of having a miscarriage.
