Accuracy of ultrasounds for dating speed dating richmond ky
An ultrasound can help you determine how far along you are in your pregnancy.Before you consider abortion or seek an abortion clinic, it is important to know how many weeks pregnant you are (the gestational age).Generally they are pretty accurate - I have seen them out no more than a week. They measured my baby on the scan and he/she measures exactly to the dates of my last period, ovulation day and implantation day.There is a significant differnce between 8 weeks and 11-12; in my honest opinion I would say I highly doubt it is out by 3-4 weeks. - She gave me the due date I had predicted all along. I went in for a follow-up today and they are saying my due date is now June 24. We were not trying to get pregnant and had unprotected sex only once that month, and I know within a day or two when that happened. When I went in for an almost 20 week ultrasound, I measured 2 weeks behind.Even when you can remember when your last menstrual period began, ultrasound can still be more accurate than relying on your last period date alone.The American College of Obstetricians and Gynecologists state the following: “Ultrasound measurement of the embryo or fetus in the first trimester (up to and including 13 6/7 weeks gestation) is the most accurate method to establish or confirm gestational age” (Committee Opinion, No. Even though using your last period date (LMP) is a traditional dating method, the accuracy of this practice depends on a regular menstrual cycle of 28 days, with ovulation occurring on the 14th day of the cycle.
Due to having wavering periods, I never really keep track, and therefore I don't know when my last period was.
My period due date for first son was Jan 19th, the ultrasound one was Feb 12ts, my son was born on Jan 13th My period due date for second son was Jan 13th, ultrasound date was Feb 6th , my son was born Feb 6th So first one period date was right ultrasound was wrong, second one period was wrong ultrasound was right lol..this new baby.knows?? For your original question, though, my US was accurate to within a day right along... And I know the dates without a doubt as we used IVF to have LO.
2nd trimester has a higher margin of error, I think could be up to two weeks?
