Hi! Assuming the question is who is the dad? Most definitely second man. The first man pulled out, you had a period, and a negative blood test. A blood test 12 days later could be a false negative but since you got your period right on time, I highly doubt it was a false negative. Sperm can live in your body for 3-5 days, so even though man 2 was only on CD 9, you definitely could have been in your fertile window. The sex was also so far apart between guys, go back to your first dating scan. Whatever you measured at that first scan, subtract two weeks, then count backwards. For example, if my first prenatal measured 8w4 today (3/22) is subtract two weeks = 6w4d. So I count back from today and conception occurred around 2/4
