Some women notice that their nipples leak during pregnancy. And that is completely normal because the breasts often start to produce milk weeks or months before you give birth.
What sort of milk is that?
The substance that usually leaks from the nipples is called colostrum. It is the first milk your breasts make in preparation for feeding your baby. Leaking is normal, and there is nothing to worry about.
How to stop the leak?
If it bothers you, you can try putting tissue or an absorbent pad (sometimes called maternity breast pads, or nursing pads) in your bra. These are available in some pharmacies and mother-and-baby shops.
When should you get help?
After your baby is born and you are breastfeeding, your breasts will probably leak milk. Some women continue to produce milk up to two years after they have stopped breastfeeding. If the fluid is bloodstained, though, you should talk to your doctor.
