Heyyy, I think u are, take a test and lemme know!
Actually, leaking nipples isn't a common sign Of pregnancy. Some of your other symptoms are however. If you've had unprotected sex then it could be that you're pregnant. Or with the wacky period and breast leakage you could have a hormonal imbalance. Either way I suggest taking a pregnancy test and Even if it comes back negative see your doctor because leaking breasts can be a sign of something more serious.
from the sounds of it you might be pregnant if you stopped getting your period. and leakage of the breast is a sign of pregnancy. they will be bigger and sore and alot of weight gain. and i think intercourse feels different after you get pregnant like your vagina feels different to your man
