HELP I CANT BE PREGNANT

Someone please reassure me that I’m not pregnant... I had sex last Monday (the 27th) and on last Friday (the 24th). He used condoms and pulled out. Both days it said there was a 3% chance to get pregnant. But now I’m 2 days late for my period. I’m wondering if it’s because I have a UTI and it may be stressing me out but someone please tell me I’m not preggo just so I can stop freaking out 😭😭
