I'm 13 days late with 33% chance of pregnancy by this app and this morning me and my so was intimate and we used a condom but right when we both went the condom broke and I have been having some weird cramps all day. I'm kinda scared that I might get pregnant but in a way I want to be. I'm so confused right now I don't know what to do. but if anyone can give advice of why I might be 13 days late with every single test coming back negative and just now having weird cramps it would be helful .
