7 Weeks Pregnant Ultrasound
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

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

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
