Okay...I'm worried. My last period was from the Sept 28- 1st of October. On the 4th My boyfriend rubbed his penis around my asshole..he said i needed to whip myself because he thought that something slid into my vagina..I took the next choice on the 5th. I bleed from the 9th to the 12th...was that my period? because I haven't had any other signs of a "period" since the 12th..
