Whose baby would it be??

Ok so I went through a break up with my ex fiancé and ended up sleeping with a friend. So I last slept with my ex cd7 and cd8 before we broke up thn cd 12, cd13, cd14, and cd15 (today) I slept with my friend unprotected and he finished in me all 4 times. Now What I’m worried about is that I ovulated early. I received what I think is a positive opk Cd 14 (going to attach a pic)

So if I get pregnant whose baby would it be my ex’s or my friend’s ??

I’m glad them rude comments got deleted cuz I swear y’all confuse me for them girls y’all can actually bully on here💅🏾
