Pregnant or just overthinking?

Evelyn

My boyfriend and I had unprotected sex three days ago and a week ago as well (August 3rd and July 30th) we didn’t use protection but he did pull out, we went in for a couple of rounds both days. The app said I was supposed to get my period on the 3rd but I didn’t. I’ve been stressing out and getting really paranoid could I just be late or is there a high chance that im pregnant?
