Advice needed

So my boyfriend and I had sex 2 weeks ago after my last period. The condom broke but he swore that no cum came inside me and rightfully so it probably didn’t. I always have that fear though, and he tells me all the time to not worry about these things and that this happened before. Well my period is approaching in 3 days, and I hope it comes. I’ve been worried! I have been getting all the signs of my period; my lower back is sore, sore breasts, and minor cramps. So hopefully it comes, and it’s not my bodies way of feeling that way before my period like always and nothing comes out? I’m scared , should I be worried if I have all the signs that I’m getting my period? I feel like even if I was pregnant I wouldn’t even get any sign with my period.
