I need help! Ok so March 2, me and my bf had sex, it lasted for only 10 seconds and we quit, because I got scared. It didn't last long enough for him to "do anything inside me". I have had two periods from that time until now and in late march/early april I took two different pregnancy tests and they were a week apart and both of them were negatives. And a week ago monday, we tried to do it again, but this time he used a condom and it was only two seconds. He pulled out and finished outside of me. My second period i had started last friday. I hope this makes sense. I think I am just overreacting and thinking that I might be pregnant. I think it is all in my head and I am telling myself that I have symptoms. Can you help me? Thankyou.
