Patient :I don't know my last period but went for a early scan and they dated me at 8.1 days gest with edd at 3rd Dec 2015 I asked when I concieved if they add 2 weeks on and she said I would have concieved around that time as this is the actually baby measurement is this correct.?
Thanks for the query.
If Dec 3, 2015 is considered to be the scan date, the period of gestation on 28-04-2015 is 8 weeks 5 days. The date of conception is roughly, Mar 12, 2015, provided your cycles were regular. The date of last menstrual period is calculated by subtracting 2 weeks from the conception date.
Hope this helped
