You conceive somewhere in the 2 weeks after your last period. You due date is based on the size of the baby, then they give you a date. But that date is from your period not conception. So if the baby is 6 weeks size on an ultra sound you conceived 4 weeks before.
Also they go by your period so if your period was october 1 then within the weeks after that you conceived, to figure your due date they say go ahead 1 week and back three months... So it would be due july 8. So if you're due in may? You got pregnant in august. Now just take your due date and go back 7 days before that. Then 2 weeks after that was conception. (during that week of ovulation.)
