I’m really scared

Ok so just lost my virginity last night and am freaking out. I know a lot of my friends felt the same way too but I just don’t know what to do and just need some advice.

So basically we did it last night, he had a condom but he came inside me with the condom on.

I started birth control almost a month ago but I’m still nervous I could get pregnant. I’m very very nervous and am literally making myself sick over this. Any advice?
