No. Gestational age is measured from the woman's last period. Even if she doesn't know when this was, the gestational age is time from conception plus 2 weeks. For example, a 'gaedd 19 weeks' will give you a due date 21 weeks in the future. You are 17(+ 1 day) weeks from conception. 19(+ 1 day) weeks from your notional last period and 21 (- 1 day) weeks until your EDD.

No, you count back 38 weeks for the conception date, but don't forget this is just an estimate.
EDD is ESTIMATED. If done by scan is 38 weeks from conception. An EDD is based on the LMP (last menstrual period) and not the date of conception. The ultrasound measurements are comparing the baby to the expected size of other babies at the same gestational age. The earlier the ultrasound is done in the pregnancy, the more accurate it will be. Hope this helps! Dr. B.
Ultrasound gives an estimate of the age of the foetus. At this stage of the pregnancy, it's quite accurate, but it's still only an estimate, and the date of conception could be a few days, even a week, away from the date 19 weeks and 2 days ago.
your conception date should be pretty accurate considering u had an ultrasound. you shouldv'e been ovulating around June 21st.
Somewhere around the end of March.
Conception date is based on your last ovulation cycle prior to when you didn't get your period. But this can be incorrect if you didn't conceive when you was ovulating. Alternatively you can have a ultrasound scan which will give you a conception date but this can be off by 5 days.
no June 25th would be the app date the sperm met the egg it can be up to 7 days before this the act of sex that lead to conception so for example if you had sex June 18 through 25 would lead to conception on June 25th. but as far as that not being your last period ultrasounds are better than lmp for timing so u take off two weeks from ur ultrasound and this will tell ur app day of conception if the ultrasound says u are 6 weeks u got pregnant app 4 weeks ago because everything goes by lmp including ultrasound so ultrasounds add on two weeks also
NO ultrasounds measure amniotic fluid and the fetus head, this would not alter you're conception date. If you wanna know you're conception date go to www.webmd.com and they will calculate the time you conceived based on you're due date. It's just an estimate. GOd bless
It is impossible to say as a term baby could be born from 37 weeks to 42 weeks of pregnancy. You need a due date from a period or an ultrasound to have an idea of conception date
