Paternity worry. please help

[ByDearAnt]

i feel i will be judged for this but as we approach birth i'm more nervous than ever, and would like the input of others. I'm sorry for how much I'm writing here also!
on day 4/5 of my menses/October 2nd i (reluctantly) had sex briefly with my ex/abuser. on the last day/ October 3rd i had a non-consensual encounter with him. he "finished" neither time, but i noticed pre-cum before the first. the second encounter was shorter, also.

from about October 8-10 i started having sex with a long-time friend/the guy i am with currently. he would finish each time with no protection. we were having intercourse every other day until the 21st or 22nd.

on November 7th i found out i was pregnant via an unrelated ED visit, with HCG of about 700. at this time they looked hard but couldn't see anything more than a teeny black dot (which turned out to have been the sac) and were even concerned because i've had an ectopic. after exactly a week i went back for another sono which revealed a tiny egg yolk, but still no fetal pole. my OB herself told me i would've conceived likely around late october and all my dates seem to align with that, but i just want to hear what you all think based on the provided info.

i already understand a paternity test would be able to tell me for certain. i just want to know your thoughts

Your baby will be with you very shortly. It's much more likely to be your current partner's child. This is a new start for you. Start living as you would wish your child to when they are adults. Don't have sex with anyone you don't want to, use contraception, be in control of your life and be responsible for your decisions as you will be for this child.

absolutely. as i stated, though, previous partner had forced himself on me.
i was a little hasty with the second, but we had known eachother forever by that point and are still going strong

Sounds like you've been through a lot.
I think it's overwhelmingly unlikely to be your ex partner, given that you were on your period. If it definitely was a period, then you can't ovulate during that time. It's chemically impossible. We know sperm can live for 5 days but you would have had to ovulate earlier than average for that to get you pregnant.
Do you know when in your cycle you typically ovulate?
All signs point to being current partner.
As PP said this is a chance for a fresh start. I hope your ex ie out of your life for good. Don't let him steal any more happiness from you. I hope your new partner treats you and your baby right.
