12/21-12/26: You haven't listed alot of detail here; however, if your due date was determined on an early US (around 5 weeks) then sex for conception likely occurred between 12/21 and 12/26. There is room for error in these dates, so if this is a question of paternity, the only way to know is paternity test after baby is born (unless blood types rule anyone out)
