What else can I help you with?
When it says that an ultrasound is most accurate at 12 weeks does that mean gestational age or the time since LMP?
The earlier it is the more accurate it is whether from conception or from LMP, but if you say 12 weeks you mean from LMP.
If you do not know your LMP and have an ultrasound and you are about 15 weeks pregnant is that when they think the LMP was or is that the baby's age?
Usually the doctors say the age is LMP. So if they say 15 weeks, it'd be about 13 weeks since conception.
What's the difference between galmp and gaedd when an ultrasound is performed?
GA is gestational age which is how far pregnant you are. LMP is last menstrual period, which is the date of the first day. EDD is estimated dte of delivery (40 weeks from the LMP) The EDD may be changed if the ultrasound gestational age differs from the age by LMP by a lot.
If an ultrasound said you were 10 5 and it matched your lmp near enough does this mean you were only 8 5 weeks Do they add on 14 days to get your lmp?
Pregnancies are always measured from your lmp so it sounds as if your ultrasound is spot on. They don't add 14 days or anything but it will be 8 weeks 5 days since you conceived
There is a 12 day difference in due dates ultrasound confirms an earlier date and LMP is a later date Which is more accurate?
I go by the LMP, but even then I had mine early.
Will your ultrasound be given in weeks from conception as you dont know when your last period was?
no ultrasounds go from lmp so no it will not go from conception it will add two weeks just like everything else if its been 4 weeks from lmp your ultrasound will say u are 6 weeks
Your doctor says that an us is more accurate than lmp because a lot of woman don't remember their lmp and that you could ovulate at different times how true is this?
Women have cycles that are not all the same length but most women ovulate 14 days before a period is due. That is what makes the difference. At 7 weeks ultrasounds are accurate to within 3 days. At 20 weeks they are accurate within 5 days When I had my first pregnancy my cycle was 36 days which would mean my EDD would be 8 days early if my LMP was used, my US agreed with my cycle not my LMP. When I had my second pregnancy my cycle was 28 days and my ultrasound agreed with my LMP. So you are saying that the ultrasound is more accurate? Yes, the ultrasound is more accurate. I did go round the houses a bit to say it.
If you dont know your lmp and had ultrasound at 5 weeks 4 days how accurate are the dates they give you?
very accurate (within one or two days)- they tell this by several different things
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.
Had an ultrasound yesterday. LMP was Nov 2 so you should be 7 weeks The ultrasound only showed you being 5 weeks pregnant you are going back next week for another ultrasound Should you be worried?
You have two due dates...one accourding to your last period and one accourding to the size of the child on the ultrasound...i think the ultrasound one is more accurate
If your ultrasound said fetal age is 7 weeks but your LMP was 9 weeks ago should you worry?
No, sometimes doctors get the dates wrong or sometimes the baby is a little ahead or behind in growth. I would go by the Ultrasound.
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.
