My guess is guy B. He placed a better bet, also closer to ovulation . Try a paternity test with him when the baby arrives.
When was your earliest ultrasound done that gave you the due date of March 9th? Depending on when the ultrasound was performed, it could give you a good indication when conception occurred.
Also, when was the paternity test done? If it was in early pregnancy, there may not be enough fetal dna to extract at that time. Have you contacted DDC and tried again?
I unfortunately can’t give a definitive answer to your question. Intercourse with man on the 13th (withdrawal or not) could have still passed sperm through. Although the withdrawal method is used widely among many couples, it isn’t a full proof method of birth control. Many women become pregnant this way. Sperm could have definitely still been alive on the 16th, when your ultrasound says conception happened.
I would definitely try to contact DDC and have another test ran if possible or wait until after the baby is born of course.
Your due dates suggest ovulation June 16th to 19th. In my opinion the no- pullout artist is more likely the lucky father
The reverse pregnancy calculator says your likely conception date was June 16, if your due date is March 9. When did you have your ultrasound performed?
I meant to say my period started on June 5th and ended on June 9th
