I have three pimple-like bumps on the tip of my nipple. They aren't sore or anything but when I squeeze them, white stuff comes out almost like a black head. This happens on both nipples.
*I'm 16 years old &have been sexually active a lot in the passed 3 months
*I didn't use condoms or the pull out method
*I have PCOS
*And I recently had a negative pregnancy test though I am showing a few signs of pregnancy such as nausea, cravings, and it being uncomfortable now to sleep in my stomach when that used to be the only way I could sleep. My lower back and tummy is almost always uncomfortable.
*I haven't had a period in 7 months due to PCOS
What could this be on my nipples?
