ok so my boyfriend and i have been going steady for about 9 months now and weve been having sex since about month 6. Its always great but my problem is every time we do, i get pregnancy anxiety the DAY after all the way up until my next period, which can sometimes be up to 20 days away. We are VERY safe and he pulls out every time AND wears a condom just to be SUPER safe, so really i should have no reason to worry but i always do! My mom is always harping on me askig me when my next period is gonna be even when it happened like a week earlier. The longer time goes on the more she stresses me out and yells at me about how i cant be having sex until im older (she doesnt know we have done it already) and it makes me even MORE worried!! Im sixteen and i really want to go onto birth control to escape this anxiety but i would get MURDERED for asking either of my parents! What can i do?
