So worried

So scared I'm pregnant, I had sex 2 days ago and I'm worrying so much, I feel sick and I'm tired!!! I've taken birth control on the morning after it happened and I've honestly never been so scared, I'm 16 & we used a condom but I think some semen got onto my vagina as before he placed the condom on he rubbed against me... Then we had sex and he came inside the condom. Would I feel the cum go inside of me if the condom split? Weird I know just stressing
