Im freaking out

Ok so me and my bf (were both in 10th grade) decided to try and have sex and we did kinda? Idk it was really clumsy but my period was supposed to start two days ago and it hasn't and I know itll probably show up later this week but thats the first time I kinda had sex I me a we used a condom... And it didnt break and we were really careful but idk I think I might just be a little paranoid.

Also me and him are both 16
