I’m beating myself up

Hey y’all I’m new here and I’m just really stuck trying to figure everything out …..today I’m 8 weeks and 5 or 6 days and my last period was April 20 and I ovulated May 9th or 10th I had ultrasounds early due to complications so as of today June 27 I’m 8 weeks 5 or 6 days give or take …. I was with my ex and I had my cycle from April 20-24th and I’m almost positive I didn’t sleep with him the 4 days leading to our breakup . Now I did have sex with my daughters father around the first of May including the days I ovulated and up until recently ….my question is is there a possibility I’m pregnant by my ex ? I know it’s literally slim to none that I’m pregnant by him but I’m just really confused and never been in a situation like this before .

Please help!
