How Is A Pregnancy S Paternity And Date Calculated?

Based off my due date, which is December 11, 2010 that would mean the day I concieved was on March 20, 2010. So does this mean that that was the time frame that I was ovulating and got pregnant from precum? Also if I had sex with someone else on the 25th, would that due date add up, to make that person the baby s father?

Expected date of pregnancy calculated by adding 9 month and 7 day in the first date of your last menstruation cycle. If you want to calculate date of ovulation than add 14 days to first day of your menstruation cycle. According to your your last menstruation was 11 December, according to this your ovulation was on 25 December.
