HELP PLEASE

So I am 6 days out from my next period and I had sex twice we used a condom and when he came he came outside of me in the condom and this was on September 6 and 7th and I’ve had these weird almost cramps that were super subtle last week and now this is the week I’m going to get my period and my boobs are on the verge of maybe getting sore and I’ve been a little emotional not really and I’m just really stressing out over my period starting and I’ve been telling myself there’s no way I’m pregnant any advice??
