I have been sperated from my husband for a year but still live with him and was sexually active with him for that year. I never got pregnant. My last period was June 4th. I have a 28 day cycle. Had sex with my husband on the 13th and then I had sex a couple weeks later with my boyfriend for the first time on the 21st and missed my period in July. If its more than likely my husbands, I want to stick with that story for my boyfriends sake, But he thinks its his and wants to know, but I don't have $400 to play house with because of my irresponsibility. Just curious beings I went an entire year w/out getting pregnant, then finally have sex with my boyfriend, and miss my next period.
