Leaking Breasts During The First, Second & Third Trimester

Throughout pregnancy, your body goes through tremendous changes. In addition to the obvious, the growth of your baby, you will experience a variety of other side effects. One of the most common side effects is the leaking of fluid from your breasts. This fluid, called colostrum, is generally clear and sweet to the taste. It is ultimately the first nutrient that your baby will receive, because you won’t actually produce breast milk until a day or two after you deliver your baby.

Some women have experienced leaking breasts during the first trimester of their pregnancy. In as few as six weeks, your breasts will have grown in size, partially due to fat glands and partially due to the increase of the milk glands. Some women have had leaking breasts as early as three or four weeks of pregnancy; however, this is not common. It is more common for women to have leaking breasts by around the end of the first trimester, sometime between 12 and 14 weeks.

Other women won’t begin to have leaking breasts until well into their second trimester. The end of the second trimester, sometime between 26 weeks and 30 weeks of pregnancy, is the most common time that women begin to have leaking breasts.

As you get closer and closer to your delivery date, you are more and more likely to have leaking breasts. In the third trimester, some women even begin producing milk instead of just colostrum, although this is somewhat rare. If you have been leaking throughout your pregnancy, you will probably leak in greater amounts as you approach your due date. Still, many women do not experience any leaking breasts until after their baby is born.

In general, leaking or not leaking during pregnancy is usually not anything to be too concerned about. Even if you don’t start leaking until after your baby is born, there is no reason that your baby won’t be able to breast feed. Still, if you are concerned that you are leaking too much during pregnancy, or believe that you may not be able to produce breast milk, you should speak with your health care provider.
