Help me

So I had sex for the first time in 2 years and it was this Saturday. I get really bad anxiety that’s why I haven’t done it so long. But yah I finally did it but now I’m stressing out and thinking something went wrong. Even tho the condom didint break and he didint even cum cause it was hurting to much. But since Saturday I’ve been breaking out (something that never happens to me), weird discharge and like some white stuff from my nipple( which has happened before). My bf said we are fine but I just need someone else to tell me it
