Ladies please read and give advice

So a little over 2 months ago the love of my life packed his things and moved out of the house leaving me empty and broken. I still am not over him and my heart still hurts but I know we will never be a thing again. I took my pain and anger out in the absolute wrong way and ended up sleeping with 2 different guys unprotected like 2 weeks apart from eachother. I regret it horribly because that's not something I would ever do, now my period is a week late. My ex an I tried to have kids for 3 years and it never happened so I'm trying to be positive and think maybe it's just late because I do have irregular cycles in general. I am now on cycle day 40 with no period in sight and I haven't been too stressed or had any changes lately so now I'm starting to worry. I know the only way to know is to take a test but I'm also scared to test because of I am pregnant I wouldn't know who the dad even was until I had an ultrasound 🥺🤦🏻‍♀️I'm so upset with myself and never could see myself having a kid with someone else let alone with a stranger . Has anyone been in this situation what should I do ?
