My nipples are really puffy and there's bumbs on my areolas, I also found some white stuff inside my nipple ? Is it dried milk? I'm a virgin and I haven't had sex protected or unprotected. However I have had a penis rubbed over my underwear and it is said sperm can't travel through my underwear but why are my boobs different ? Would I begin milking breast milk on the first week of conception? Or am I being paranoid and there's still no chance I'm pregnant
