Guy 1 or 2?

[Worrywart29]

My period was February 19 to 26. On cycle day 5 feb 23 I had unprotected sex with guy 1. Guy 2 was Feb 26 and almost everyother day after. My shortest cycle is 29 days. My average cycle is 31 days. My due date is November 25th. It has never changed.

Unless you ovulated unusually early, the pregnancy would be the result of sex with Guy 2. When in your pregnancy was your first ultrasound?

[Worrywart29]

Covid was happening so they weren't doing u/s. 21 weeks was and they kept same due date because it was within margin of error. My app shows I would ovulate on March 5th so even if my cycle was  5 days sooners it would still be off by 7 sed

I had taken opk in past months and I have never gotten positives before cd 15. I've gotten period on the 19,20,21 since I was 16 depending on month length. So basically a 30 to 32 day cycle. Nothing extremely short or irregular. So I'm thinking cycle day 5 intercourse is unlikely with conception of guy 1 unlikely even with sperm survival

30to 31

It sounds unlikely to me, too, except that by 21 weeks the "margin for error" the doctor used is pretty big (at least a week and a half); which brings the first guy back as a possibility except for the way your cycles behave.

So, definitely do DNA testing once the baby is born, in order never to have to wonder. Ask the first guy to do a test, on the basic grounds that the two of you had sex in the same cycle that produced the baby.

If you don't want the second guy to know about the first guy (i.e., if you don't want him to know there is any question at all, since it seems like he must be the dad) ask him to do a DNA test when the baby is born because you need the information to be in the baby's record. Tell him that if you were married (to the second guy), the law will see him as the dad even in the absence of a DNA test, but it doesn't work that way when the parents aren't married, and the baby needs this for legal reasons.

It sounds (from the way your periods are) like the second guy will come up in the DNA testing as the dad, but you should test anyway. Then you can forget you ever worried.

Ya I got the guy to give me swabs it took a little convincing. It was causing me more anxiety thinking I would never know. I basically told him imm 99 percent sure its not his but 1% unsure. Based on it is possible because of sperm survival and the possibility of ovulating that early but statistically unlikely. I did alot of research with fertility charts and opk progression and for my own sense of comfort. I saw very few women ovulate onbefore cycle day 11 even with shorter cycles than mine. In fertility awareness if you have never had a cycle less than 25 days cd 3 to 5 is generally safe after that you should monitor cervical mucous. But scary to think of worst case scenario. I would never wish the predicament on anyone.

You said you "got the guy to give you swabs." But you are still pregnant, isn't that right?

[Worrywart29]

Guy 2 is the father. What a waste of a pregnancy!

[AnnieBrooke]

Do you mean, it was a waste to do so much worrying when it seemed pretty clear Guy 2 was the father?

[Worrywart29]

When you have anxiety you don't think rationale. Anything is possible some things are just less likely. Its not like I had ultrasound evidence like other women. I had a baby that was almost 11lbs so yes I had reasonable fear. I only had that I have ultra regular cycles doesn't mean that one was going to be

[AnnieBrooke]

I was just asking you what you meant when you said "what a waste of a pregnancy!". Assumed you meant that in retrospect, the worrying was a waste of time? (Not that the pregnancy was a waste, since it produced a baby?)

[Worrywart29]

More like was my last pregnancy and I made it a miserable time instead of a happy time by making one impulsive decision when I had been extremely careful the last ten or so years of my reproductive life.

[AnnieBrooke]

Well, it's regrettable that you made yourself miserable, for sure. But just ask anyone who has dealt with infertility -- you're the lucky one, and would be even if you had cried every day you were pregnant, because you have a baby now and that is a wonderful thing. My warmest congratulations to you, and best wishes. :)
