I can't be pregnant you guys and I think I'm over thinking it because I already have irregular periods and we used a condom. But like march 11 me and my ex had sex and used a condom and then the next day I started my period and the April came and I skipped it but there was some light bleeding but it never really came and I'm really nervous and I'm scared of pregnancy test because I'm scared I'm gonna look to see what it says and it be positive so what do y'all think ( his *ick didn't come near me except for some pregam action with our clothes still on and I can't think of any other way besides him fingering me and him jacking if before and having a little bit of cum on his fingers [which is almost impossible] so anybody wanna calm me down or tell me what y'all think??
