I need help you guys. This is a very long and embarrassing story ,but here goes nothing

I left my Ex , let’s Call Him R, on September 22nd exactly. We had intercourse that day and a plethora of days before that date throughout the month. I had a Period on September 25 -30th

..... I had a date and I really enjoyed myself on October 8th with a guy , let’s call him G, on the 10 of October things got a little heated and he ate me out in his car which lead to us TRYING to have intercourse .... he has penis issues he told me and he just couldn’t get hard for the life of him. I tried to sit on it three times to no avail so we gave up and he told me later on that night that he went home and ejaculated ( idk if that’s necessary information , but it may be)

Let’s fast forward to now November 5th I woke up and the first thing I did is throw up. I knew something was off . I took 4 pregnancy test and all were positive. Clear as day.

I went to the doctor November 6th for a pregnancy confirmation. They told me I was indeed pregnant . The doctor asked when was the first day of my last period so I told him Sept 25th. He said “ I believe you are approximately 6 weeks.” They give me an ultrasound and after the results they the tell me I’m 5 weeks. I immediately told my ex I was pregnant and is he going to be there etc. what about is etc .

R doesn’t really want a baby and so now I feel like total shit because I just assume it was his and forgot about my “ altercation” with G .

No G and I didn’t actually have Sex But Precum is a thing.

So based of this info ( and I know you guys aren’t doctors etc etc etc I’m just asking for Educated opinions here , of course I have another ultrasound scheduled, but I’m racking my brain for something until then ) who is the father ?

Any help is much Appreciated ❤️❗️

P.s. my cycles are irregular and my cycles can vary between 33-41 days sometimes.

I don’t see my doctor until next week.

PSA: I’m not trying to pin this Baby On R. I actually would love if G was The Father. We are very compatible and are already thinking of our future . I just don’t see how it’s possible because he couldn’t get hard he was FLACID he held it up on the third try to help it get in and it went in for 1 second as soon as I tried to go up to begin “riding” it popped out. I got up and we gave up. I just don’t see that getting me pregnant and I have PCOS so for me pregnancy has never been easy. I am going to get a DNA regardless. I just want to ease my mind and probably help myself figure it out so I can have the correct person to be there at the birth and be here for me in General. I spotted on the 5-7 thinking my period was on the way it stopped. And then here come the 25 and 26. I was spotting very lightly both these days , but again I thought it was my period coming and I believe it was because on the 27,28, it got heavier not as heavy as usual but not like unusually light or anything so I thought nothing of this. On the 29,30 I experienced the “end” of my period T.M.I I know but you ladies know what I mean by the “ end “ gunk . My periods usually last 7-8 days. But I have been stressed.

In the end I will update when I get more ultrasounds etc. and also with who the father was. I’m not going to Hide anything from either guy or just “ pick a father a DNA will be done. I just don’t want to approach G incorrectly because I see a future with him.
