I'm 24. My child is almost 3 years old. I haven't been breastfeeding since he was 3 months old because I had nipple thrush, which literally turned my nipples into raw flesh in a month... I finished breastfeeding with pills because it didn't work on its own. My breasts were rock-hard, engorged, milk flowed like a river... here's the thing: until today I thought that my breast milk, which can still be expressed from my breasts to this day, was something like a gift! Like, since there were wet nurses in the family, I'm the same. But in a conversation with a friend, and while looking at other nipples and showing "expertise," milk shot out of me in a stream, and doubts crept in — is everything okay with me? What we have: milk can be expressed from either breast, but mostly from the left (there was thrush there, if that's important), pressing doesn't cause any pain, and overall the breast doesn't hurt much. There are painful sensations in the first 2 days of my cycle, then they disappear. The milk comes out both white and clear. From the right breast it's colostrum. Question: if it doesn't bother me, do I need to rush to the doctor? What could this indicate? I have excess weight and I'm taking antidepressants.
