Okay so I'm not sure if I'm pregnant but I don't want to make a big deal because it is soon to tell. I'm 16 and me and my bf had sex Sunday April 24th. When we got done he said that the condom had slipped off inside of me. I started freaking out and crying because I'm always super paranoid about it all the time. He said everything is fine cz nothing got in/on me but I don't trust it. I'm not on birth control because my mom has yet to call a doctor. My period is late but I'm always irregular I was supposed to start April 16th according to this period app I use. My last period was March 21st somewhere around there. I'm not sure when I ovulate bcz I'm so irregular and I'm just scared because my parents are not supportive at all and I'm not even supposed to be having sex without birth control my boyfriends mom knows about all this stuff because I can go to her about anything which is great. I have a pregnancy test I'm just waiting because it has only been 4 days since we had sex. Could I be pregnant even if I'm not sure if I was ovulating
