This is the seventh time I posted about this because I’m so paranoid

This is the seventh time I posted about this because I’m so paranoid so if you already saw this I’m sorry

Back in august 4th I had sex for the first time (I am 16) we used and condom and he didn’t finish inside me (it wasn’t long either it was like 5-10 minutes)

About a week later I got my period it was totally normal 5-7 days no problem

However

Since then I haven’t gotten my period. I am currently around 34 days late. About a week ago I took 3 pregnancy tests from the dollar store all were 100% negative.

Yesterday my boobs hurt really bad and I don’t know if that means my period is coming or if I’m pregnant.

I thought maybe I just skipped a period (if that’s the case my period should come in two days)

Do y’all think I’m not getting my period because of stress, or am I pregnant???
