IS IT POSSIBLE?!

Kelsi • Struggling on this journey called “Life”
okay so twoish weeks ago I had sex during my fertile window which at the time was 33% (high). He wore a condom and he never came inside of me. He pulled out (with condom on) and then came. I've been having weird stomach pains and he's freaking out thinking I'm pregnant. How can I assure him there's no possible way?
