By LMP I am 7 weeks pregnant. Ultrasound at 6 weeks 3 days showed irregular sac, no heartbeat or yolk etc. No flow around sac. Hcg rising. Miscarriage?

Early pregnancy: It's too soon to be sure what is going on. Often a woman will ovulate later and the lmp will not be accurate. The best option is to repeat the beta-hcg every 48 hours until 3 results are performed and a repeat ultrasound 1 week after the previous was done. That will usually solve the question. ...Read more

Sonogram (Definition)

An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more

When 1st trimester ultrasounds date pregnancy how do they base the gestational age? Do they assume conception occured on cd14?

When 1st trimester ultrasounds date pregnancy how do they base the gestational age? Do they assume conception occured on cd14?

US: First trimester ultrasound is based on biometric measurements only, the embryonic crown-rump length, which is extremely reliable when done by a skilled sonographer. No assumptiosn need be made at all. The ega is however reported correctly, by convention, from the first day of a hypotehtical last menstrual period; so in that regard it 'assumes' conception on cd 14. ...Read more

Hello doctors, I just had an ultra sound at 7 weeks pregnant. They told me that I was carrying two but only one had a heartbeat. What now ? I'm scared

Confirmation: While it is certainly possible that you have lose one of your little ones, it is certainly necessary to have it confirmed by another ultrasound. Early pregnancy loss of one twin is not uncommon and if this occurs, the body will naturally "reabsorb" the twin. I am sorry for your news. ...Read more

I am 7 weeks pregnant.Been cramping and spotting and bleeding.Sonogram shows no heartbeat yet.Is it right time or to early to see heart?I take progest

Can't tell: If the sonogram was done endovaginally you probably have an early pregnancy failure (spontaneous abortion). If it was done transabdominally you might not see a heartbeat at 7 weeks. And should repeat in a week. ...Read more

Does 1st trimester ultrasound have margin of error up to 7 days because of the equipment/skill of tech or because fetus can grow at dif rates?

Does 1st trimester ultrasound have margin of error up to 7 days because of the equipment/skill of tech or because fetus can grow at dif rates?

Margin of error is: Margin of error is 8% - so it differs the longer you are pregnant...so for example at 10 weeks - you are 70 days pregnant - which 8% means a 5 to 6 day error.
If you are 20 weeks - the error is 140 days x 8% which is about 11 days of error .....so you need to do math ...Read more

What is the accuracy of an abdominal ultrasound at 7 weeks? Is it greater than the standard of +/- a wk for 1st trimester since preformed abdominally?

What is the accuracy of an abdominal ultrasound at 7 weeks? Is it greater than the standard of +/- a wk for 1st trimester since preformed abdominally?

Probably not.: First trimester ultrasound is accurate to about a week. This algorithm is based primarily on crown rump length. The date is as accurate as the measurement. That being said, a transvaginal exam is probably a bit more accurate, but it's only as good as the measurement. ...Read more

What is the due date accuracy w/ 1st trimester ultrasound?

What is the due date accuracy w/ 1st trimester ultrasound?

It depends: It depends on what was measured and when. Very early, the sac diameter is accurate to ±5 to 7 days. Later, a measurement called the 'Crown-Rump-Length' at 7 to 10 weeks of gestation is the accurate to ±3 days. After 10 weeks, the accuracy of the CRL falls slightly with a margin of error of ±5 days at 10 to 14 weeks. ...Read more

Is it possible for ultrasound in pregnancy to give inaccurate dates? I think if further along by 3 wks, 1st trimester

Is it possible for ultrasound in pregnancy to give inaccurate dates? I think if further along by 3 wks, 1st trimester

Not 1st trimester: A professionally done first trimester ultrasound is accurate to +/- around 3 days, so there is no way to 'mistake' dates by 3 weeks. Ultrasound by a non-qualified individual could be off by this amount I suppose, otherwise they are extremely accurate. ...Read more
