Messy situation

So I really need help and I’m hoping not to have any negative comments.

I’m 33 weeks pregnant now and I’ve been okay doing this alone.

So my last period was 6/6/19. I was fertile June 13-19, ovulated June 17, and had sex with person 1 June 17 & 18.

I took plan B not knowing it wouldn’t work if the egg already released or whatever. I was misinformed about how it works so I thought I would be good. Took plan b June 19.

Had sex with person 2 June 28. Ended up having some spotting/old blood on June 30.

My period was supposed to come July 3, and I tested positive for my pregnancy test July 7.

I’ve been so certain that it’s person 1’s baby... but now he’s questioning me about it again and it’s confusing me all over again.

Will most likely do a dna test once the baby’s born. But just wondering what you guys think... more so who you think the father is?

Again, please no negative comments. I already feel horrible.
