so the best way to find out is to do the following: 1. whenever they did the ultrasound you should subtract 7 weeks and 4 days. this should give you the time when you ovulated. this will give you a very good idea when you conceived. you need to understand that ultrasound at that time is accurate up to one week. so the date you come up will be within one week of the actual date you conceived. .
i recently found out i’m pregnant. they said that i'm 9 weeks and 4 days. how can i find out when i conceived? . the doctors did an ultrasound and from the measurements of the baby. i've never really kept track of my periods because they are so irregular.
