What should I do??

So I'm a minor, and my bf and I did it with an extra thin condom from Trojan, I always tell him to pull out once he starts feeling it so we can be extra safe right? Well he pulled out and then we both realized that the condom had broke and I was freaking out. I took a plan b like 30 minutes after that happened. On the box it said that you might get your period a week early or a week late. Well I have 3 days left of when my period should she happening, so I'm really hoping that it's a week late like it said. I'm just really scared and was wondering what your thoughts were
