hope I'm not pregnant

Liza
So, I'm a married mom of 3, visiting my husband overseas (military). Haven't seen him since July so of course we were going at it everyday , a couple times a day, when I first got here. We'd been saying now wasn't the time for a 4th child, but neither of us honored that upon my arrival. We didn't start using condoms until about a week into it 😒 (I know; no judgement needed). Even then, he'd wanna go again after. Now, as this 3 week trio comes to an end I remember just why we shouldn't have another kid. I was forced to bring in the new year on a boat with a coworker he sought an affair with. Grudges have been long, fights have been even worse (verbally and physically). He tried to recant the things he's said and justify the things he's done...but I'm tired. I have no words for him. Nothing gets through. It's like I'm not allowed to have feelings. I get attacked for them...verbally, emotionally, mentally, physically. My period did come since I've been here. Came 4 days ago and is now over. I took this to mean im clear of pregnancy, as I've never had my period while pregnant. Is this a safe assumption??
