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.
What else can I help you with?
When was conception date if due date by ultrasound is 1 of Sept?
November 24, 2011
When an ultrasound gives me an estimated due date do i count back forty weeks to get an estimated conception date?
No, you count back 38 weeks for the conception date, but don't forget this is just an estimate.
Is the EDD given to you on your scan date from your LMP or by the date of conception?
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.
If an ultrasound showed you were 19 weeks 2 days pregnant can you count back to see when you conceived?
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.
Judging by an ultrasound at 8 weeks im due on March 14 which means i concevied on June 21. how accurate is the conception date i was with someone on June 14 and then with someone else the 17-22?
your conception date should be pretty accurate considering u had an ultrasound. you shouldv'e been ovulating around June 21st.
What would the conception date be if an ultrasound today said the baby is 9 weeks and 5 days old?
Somewhere around the end of March.
When was my baby conceived if on July 21st I was 11 weeks and 1 day according to my ultrasound?
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.
When was your estimate conception date if your due date is march 18 2009 but you did not have your period June 11but the doctors say your conception date is June 25th is that the day you had sex?
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
Would excessive drinking the first trimester alter the measurements of ultrasound to determine size and conception date And if so how many days off could it be?
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
When did you conceive if you gave birth on April 6?
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
