A question on ultrasound following my 1st question?

Question

When your adding the dates meaning conception, do you subtract 2 weeks from the weeks along that your u/s states? My u/s does not even state my EDD. The last u/s I had June 11th just gives measurements and weeks of 19 and 3 days.

Answer 1

Its 40 weeks from the date of your last period, although if the scan has on it 19w 3 d then that is probably (most likely) what you were on the 11 July.

Answer 2

Do not use the ultrasound for dating. Take the first day of your last period and count forward 42 weeks if you are a first-time mother. This will give you the most accurate dating. Best wishes, G
