me and my boyfriend had sex with a condom but it slipped and the cum went on my butt . We had sex right on my last day of my period, bleeding on the last day wasnt heavy either. but to be sure i bought next choice. 4-5 days later i had spotting for 2-3 days. . I also took plan b on january and my period came on very early and after that it started to come a day earlier than expected every month. however I'm worried cus my period is always on time and the couple of months it was coming a day earlier than expected, my cycle is like 28 day, so could i be pregnant? i cant be on BC cus i have lupus and BC gives us lupies flare ups. my period was suppose to come today so its a day late :/
