I was wearing a bra for like two days without taking it off and just now when I took it off I felt tenderness in my breast. Could wearing the bra for the long period of time cause this? I had unprotected anal sex this week and some of his cum may of been wiped on my vagina when I wiped with toilet paper when I went to the bathroom  could the tender breast be from that? Or my final thought of chase could be I'm getting my period in 7 days but usually I don't get pms until 3-4 days at most before my period (I'm 16 I don't know if that makes a difference with anything maybe growing pains lol i wish)
