Question?

Are sore breasts normal a week before period? My period are about 26/27 days and on the last day of my fertile window, I had protected sex. The condom broke towards the end but he didn’t cum, he pulled out immediately. We know precum is still an option (he said he can tell when it comes out but didn’t feel anything and wasn’t that hard or we didn’t do it long enough for precum to come out since it does take some time) but an extremely low option. I’ve read sore breasts are normal about a week before. They just started getting sore today, as well. Should I be worried at all?
