Question

I was reading thru questions asking about "Who is the father?" One of the questions asked seemed very similiar to the situation that I'm going thru. I was hoping you could help me calculate using the one suggestion given to a woman that is in the same situation I am in. I have the dates of conception, one is on May 11, 2008 and the other is the next day May 12, 2008. My due date is between March 2, 2009-March 6, 2009. One is from a sonogram and the other from the last day of my period, which to be honest, I'm not quite sure about the exact days of my last period.

The suggestion given to this woman was to give the date of conception, subtract three months, and subtract seven days from the due date. Like I had mentioned, on the sonogram that I had done on September 23, 2008 I was 16 weeeks and 4 days pregnant. Will you help me determine which man is the father of my future baby, please.

Thank You,

Dora

Answer

It is not possible to determine which date you conceived by ultrasound measurements or mathematical calculations, as they are just a day apart. You could have conceived either day, based on the ultrasound, and due date you are given.

I do not know your situation, but may I suggest you focus and plan for your future, and your child's, regardless of who ends up being identified as the biological father? And if you are planning a future with one of them, it is much more important who would be the better father, than whose sperm resulted in this conception.

I wish you the best….
