How did you get the due date, did the doctor base it on an ultrasound?
Last year I had a baby born December 21. My lmp was March 14 and I conceived end of March - beginning of April. My due date originally was Christmas Eve if I remember correctly.
If it helps I conceived in the 3rd week of March and my due date is December 19th
I punched your due date into an app and it gave me end of march - beginning of april. Doesn't mean it's right though. You could have ovulated earlier. I still recommend a dna test just to be sure, instead of taking a stranger's word for it.
You were more than likely to be fertile roughly between the 7th and 13th depending on when you started. And sperm can live up to 5 days in your body depending on the condition so more than likely he is the father
I would guess it was whoever you slept with after but the only way to know for sure would be to do a dna test. I'm not a doctor so I can't say for sure it's either guy a or guy b's baby cause I could be wrong. Best to be honest with them both and wait til the baby's born to do a paternity test.
I asked my doctor the same question and she keeps telling me around the beginning/middle of March. So technically you're saying it may not be the guys baby
You likely conceived between March 25-April 2...somewhere in there...depending on your cycle.
