Probably not: If there is a fetal heart beat, then the pregnancy is likely normal. The gs measurement is not a reliable predictor of gestational age. The fetal heart beat is usually detectable by ultrasound by about 6 weeks gestation and by external doppler by about 9 weeks.

IUP: The ultrasound is more accurate at this time so you conceived earlier. If you aren't having any symptoms, the pregnancy is okay.
