I haven't gotten an ultrasound yet since I was very regular and positive of my lmp date my midwife will only do the 20 week anatomy scan. But with my first the due date was Sept 29th based on lmp, he was measuring a few days earlier, but they kept at the 29th since it was within 5 days. He was born on Sept. Babies are on their own schedule, lol. Went to the doctor's at what should have been 7w6d but was measuring 7w1d. Makes total sense for when I think I ovulated and doctor isn't concern in the slightest. This time mine were pretty close.

With my son they pushed my due date back a week at my ultrasound, but it made sense since I didn't get a positive pregnancy test until a week after I missed my period. I thought I was due March 13, after ultrasound they changed it to march We'd be really keen to know more about your studies — and what you have learned. You're right that we did include 'anecdotal stories' in our article. We used them to illustrate the key points we were making in the articles but the quotes we used were all centred on the real experiences of pregnant women posting in our forum.

We are confident that we are not using these quotes to 'misinform women', as the key points in our article were all sourced from expert monographers. It's interesting that you say that ultrasounds between 8 and 10 weeks are the most accurate. In the UK, most pregnant women don't have an ultrasound until they are at least 12 weeks pregnant. Perhaps you are based in the US, or another country, where ultrasound practice is a bit different? We use cookies to improve your experience of our website.

How accurate is ultrasound in dating a pregnancy?-Dr. Nupur Sood

Ultrasound measurements of the cervix, the passageway at the entrance to the uterus that opens up to make way for a baby during delivery, can reveal whether labor is likely within the next week, according to a new study. The method is safe, and women already get frequent ultrasound scans during pregnancy , said study co-author Dr.

Though most women are given an official due date, it is often just a rough estimate. Only 5 percent of women deliver on their due date, according to American Academy of Pediatrics.

How far off were your dates? US vs. LMP

A healthy pregnancy is, on average, 40 weeks from the last menstrual period, but in reality, most babies come sometime between 37 and 42 weeks gestation. For many women, that five-week window creates a waiting game that can feel unbearable.

Women with little paid maternity leave may want to work until the last possible moment they can. Those whose due date has come and gone may wonder whether they should have labor induced with drugs. And pregnant women who already have other children often scramble to find child care during labor.

But there haven't been reliable methods to tell a woman exactly when her baby is coming. Cervical checks, in which a doctor manually feels the length and softness of the cervix with his or her fingers, are typically not very reliable, Berghella said.
