Has anyone experienced this or know what the cause may be? I had protected sex three weeks ago, only problem is when he pulled out the condom got stuck inside of me, we worried that cum may have gotten on or near my vagina & after doing research I found that some people have gotten pregnant this way. About a week later I got my period so I assumed I was in the clear but following this my breasts have increased in a cup size and are sore to the touch. I have taken two pregnancy tests which both came back negative. Anyone have any thoughts as to what this could be or a similar experience? Thanks!
