Me and my boyfrend had sex 2 weeks ago and now I'm missing my period. We used a condom and it didn't break, also I was on the pil but I'm very bad at remembering to take it and I probably had forgotten a few. I took a home pregnancy test three days after I was supposed to have my period and it came back negative. I'm still worried... Could I be pregnant? If I was taking the pill but not correctly BUT I also used a condom, what are my chances of being pregnant?
