A couple of weeks ago the day after I got off my period my boyfriend and I had sex, the condom broke and he came inside of me so we went and I took a plan b pill. I started my period again a couple of days later and I just got off a couple of days ago. My fertile window is in 11 days but we had sex again today and the condom broke and the same thing happened except for I didn't get the pill this time. A lot of the cum came out of me and I was told it's not likely you will get pregnant this soon after your period but I'm still worried. Any advice?
