If an ultrasound says you are 17 weeks and 3 days pregnant is that the day you conceived or would it be that date plus an extra 2 weeks?
That means it is the date conceived (or within 48 hours of). It is never right on, but within a week of. Go by what the ultrasound says. No, if your ultrasound says 17 weeks and 2 days that would be that date plus 2 extra weeks, that is around the time of your last period, unless you have irregular periods or conceived straight after a miscarriage or something. The length of pregnancy is always measured from your last period even by ultrasound.

If you are 7weeks 4 days by your LMP and you have an ultrasound and by the fetal measurements you are 7weeks 4 days did you most likely get pregnant before your LMP?
No. Doctors (and other medical professionals) measure pregnancy in terms of LMP. If you are 7 1/2 weeks pregnant according to your doctor, you probably became pregnant about 5 weeks ago. This assumes you have the standard 28 day cycle, and became pregnant at mid cycle. LMP is not an accurate way to date a pregnancy. If you are in doubt, an ultrasound before the 18th week LMP is the most effective way to date your pregnancy.
When they do a sonogram can they know exactly when you got pregnant?
If the ultrasound is done in the first weeks of pregnancy it is possible to date the embryo within a few days, an ultra sound done later is not as accurate for dating purposes.
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.
LMP claims I'm 9 weeks and 5 days pregnant. ultrasound claims 6 weeks 1 day. What's going on?
ask your doctor
