I fucked up hard and the paranoia has hit, thoughts?

Se

Long story short 9/26 I broke up with my boyfriend who I’ve been having unprotected sex with for the last two months (never been pregnant or much of a late period)

My cycles are on the dot with prediction so I’ve never thought much of it. I’m not late yet but I’m not getting my normal pms and af is due in 4 days. I did take opks this month (no bbt) and had a peak on 9/19.

Here’s where I fucked up. We were in an open relationship (with rules) and one of those rules being condoms with any other partner. Well first time I had sex with another man was on 9/18 and the condom broke at some point. Yay me.

So I said my period is 4 days out, only symptoms I’ve had was not being able to get out of bed yesterday, like I slept 18 whole hours because I’m so exhausted. Then the heartburn? It’s been since 9/26 that that’s been going on.

Other than that I feel totally normal. I took two tests today though
