pregancy or plan b?

I need help with no judgement. I am not on birth control for health reasons. The days with the hearts my bf and i had protected sex with a condom tht did not fail or break (see pic). Except on the 11th we had unprotected sex, he didn’t finish at all but i took a plan b after to be safe. My period is now currently two days late according to the app prediction. my boobs are very sore to touch, but that usually happens before my period too. I have taken an early result pregnancy test the past three mornings- they have all been negative. I’m just wondering if i’m just testing too soon or if my period is just whack bc of plan b. i’m just a very anxious minded person so this wait is killing me.
