insights?

We had sex ONCE this month on my predicted ovulation day (Baded on app) We used the condom from beginning to end & he told me he knows what his doing. It's a new condom (we just got it that day as well), he slightly pinched the tip before making its way in, he removed it carefuly for it not to leak or anything, the condom is the right size etc etc. We checked it the outside of the condom was completely dry.

Now my cycle varies from 27-35 days. But sometimes I'm a week late, a week early, 9 days late whatever. My last period was 9 days late and I'm late again on this cycle, I'm currently (2 days late based on this app) . My boobs started to hurt when my period was supposed to show and i had dull cramps.

I honestly believe that I'm not pregnant since we used protection and used properly. I'm aware that condoms dont just break easily right?

I just want to relax and agh im anxious lmfao
