What else can I help you with?
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.
Which is the date of conception on an ultrasound?
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.
How soon after conception will you skip your period?
u will skip ur period two weeks after conception and ur pregnancy test will be positive two weeks after conception
Your girlfriend is pregnant and on the ultrasound said GA edd 19 weeks and 0 days but that would place conception to almost 3 weeks before you had sex what does this mean?
They count the weeks of pregnancy back to the last date of the first day of your menstrual period, not to date of conception. For example, I am considered to be at 15 weeks. The first day of my last period was 11/25/08 and the date of conception was anywhere between 12/9 and 12/16
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
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
My date of conception was August 8 2008 so how far along am i?
As of September 19, 2008 (this Friday), you should be 8 weeks along. Gestation is calculated (at first) by counting forward from the first day of your last period, and date of conception is typically assumed to be 14 days (2 weeks) after that date. A more accurate date can be given by the Sonographer at your first ultrasound, by measuring the size of your fetus.
Think Im 6 weeks pregnant but ultrasound says 4 weeks Can this be?
I was told the same thing. Based on my lmp I am 6 weeks but I had an ultrasound done 2 days ago that said I was 4 weeks. I wonder if I am 4 weeks along because that is the time of conception since you dont get pregnant the day of your period. It is usually two weeks later when you ovulate. Let me know if you have heard anything
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.
Why are 2 weeks taken off your ultrasound scan age?
Because it's about 12 days of conception
You started your period December 1 and ended December 6 your ultrasound says you are 9 weeks pregnant when did you conceive?
If your period started on December 1 and lasted until December 6, you likely ovulated around December 15, assuming a typical 28-day cycle. If your ultrasound indicates you are 9 weeks pregnant, that would place your conception around December 15, making your estimated due date around September 24. The 9 weeks of pregnancy typically counts from the first day of your last menstrual period (December 1), not the conception date.
Is an ultrasound scan measured from your last period or when the baby was conceived?
Hi An ultrasound provides a picture of the baby in the womb. The date of conception could be intelligently guessed at by your gynacologist, probably to within a couple of days if not better.AnswerThe date of conception would be calculated by the professional and the length of pregnancy is found by working back two weeks before this.Ultrasounds have only been around for thirty years or so and before that the only way of calculating the length of pregnancy was from the first day of the last period - on average two weeks before conception as we now know.
