im scared

Ashley

I had sex with my bf on Jan 25th we had multiple rounds (6) and we only used condoms for 4 out of the 6. I haven’t gotten my period and according to all my different calendars i’m 5 days late and i’m not on bc. Im 17 and my parents don’t know i’m sexual active. I don’t know what to do. Maybe i’m stress that’s why it’s not coming ? im taking a test tomorrow to make sure if i am pregnant or not. But i need advice in how to tell my parents or do i keep it from them? I don’t want to lose any trust between us.
