I will assume you are talking about December 25th 2010. It depends whether December 25th was actually your due date or not. If it was, it makes your estimated conception date April 2nd 2010. However, this could be wrong by a couple of days.
That would make your conception date somewhere around March 2011. However, to be more accurate you would need to state your exact due date. It also depends on when you actually ovulated.
I will assume you are talking about December 18th 2011. If so, your estimated date of conception is March 26th 2011. This date is give or take a couple of days though. It should not be relied upon to determine paternity.
That makes your estimated conception date March 10th 2011. However, this date could be wrong by a couple of days. It depends on when you ovulated.
I will assume you are talking about December 3rd 2011. If so, that makes your estimated conception date March 11th 2011. The estimated conception date is not always completely accurate. It is often wrong by a couple of days.
