Anxiety and reassurance.

I’m trying not to panic or anything because I struggle with really bad anxiety. My boyfriend and I had sex on September 8th (3 days after my period ended) we did 3 rounds and all 3 were a new condom and pull out. Then yesterday we had sex again, 4 rounds and again all new condoms and pull out in every one. Yesterday was day 2 in my predicted fertile window... he pulled out and we checked the condoms so everything is probably fine right? I’m not able to go on hormonal birth control because the hormones mess with my thyroid and make my anxiety worse. I know this is real repetitive but I just sometimes need reassurance...
