About 3 weeks ago, I was pressured to have sex with my boyfriend. We tried having sex but it didn’t fully go inside me (we used a condom), I’m scared because I’m 2 weeks late for my period. I have irregular period and I don’t have any other symptoms of pregnancy other than late period. I have also not done a pregnancy test because I haven’t even told my mum about this, I’m so scared. I don’t want to be pregnant, I’m only 16. My friends think that i'm not because i have been exercising a lot and eating less, this question has literally been stressing me out so much!!!
