Overreaction

Melissa
Alright ladies, I always overreact so my boyfriend and I have dated for six months, I am a virgin and he is not. He wants to have sex, which I'm totally okay with but I'm terrified of getting pregnant. I am in nursing school so I do not have time for a baby. So should I be this nervous to have sex? 
P.S. I am one month into a progesterone only pill and we would use condoms
