I mean I had period since I'm 12 and it's not irregular now that I'm 18 it became very irregular.. Last January it came early (1-8-17) , on February a week late(2-13-17) and in March it came on the last week ( 3-28-17) does it possibly because I had dry sex with my bf? We didn't actually had sex but he fingered me now I'm feeling weirded out and really scared . Is it possible that I'm 3 months pregnant??
