Yes, November 11 doesn't rule out either person either. Since the baby will be here any day, what plans do you have to talk with the men? Will you simply do DNA tests with both of them? Because that's your baby's legal right.
If your periods always come about 28 days apart, then there is no way to differentiate between the two men by the dates. Counting back 14 days from March 1 (given the leap year) suggests you ovulated on or around the 16th. (I was asking to see if your dates might point to an earlier ovulation so as to rule out the second guy, but no.) When you ovulate, your egg can last 24-36 hours in your body, and the guys' sperm could last 4-6 days, so both men's sperm would have been in your reproductive tract and viable at the time when you ovulated. Did you have any early ultrasounds? If so, what due date did they give you?
Hi, when did your period begin?
It doesn't matter when it ended, but if your menstrual months are super regular at 28 days every month year in and year out, you might be able to try to figure it out using the date when your next cycle was expected and counting back.
