i’m scared i’m pregnant and don’t want to be

I was kinda forced to have sex with my ex, i don’t blame him but i had told him before i didn’t want to. i wasn’t ovulating (2-3 days after my fertile window and im usually a regular period haver) we didn’t twice unprotected and he peed inbetween and didn’t cum inside. i’m really scared and i was supposed to get my period yesterday. I’ve been really gassy and have been pooping a lot if thas any help 😭 (i know it’s not) i feel like i have a few cramps which is not unheard of for me the days before my period but they were so faint i think im just gaslighting myself. i know i was irresponsible but i had really not planned to have sex, i don’t want his baby and i don’t want to be with him unfortunately he’s suicidal and ill feel to blame if anything happens? any advice or reassurance? i’ve been in a similar situation before and had delayed my period from stress. i’m currently only two days late and had sex on february the 8th, my last period was ended on the 23rd/24th january and according to my app i ovulated around the 31st jan to the 5th february. Thank you so much for any advice. i’m aware i can only find out im pregnant with a test but would love any advice or reassurance.

Edit:Also just an additional possible factor; I’ve been doing a lot of exercise this month as I started going to the gym again after 8 months.
