Approach: Transvaginal ultrasound is around 8 weeks transabdominal is around 10 weeks.
Dr. Bruce J. Stringer
Radiology 47 years experience
Varies: On transvaginal ultrasound fetal heart activity can be seen as early as 5.5 weeks but more typically after 6 weeks and always after 7 weeks in live pregnancies. In very early fetuses, on trans-abdominal sono early fetal heart visualization is complicated by uterus position, large patient size, and bladder filling.

Should I be concerned if I am not feeling fetal movements at 28 weeks?

No: You should talk to your doctor. Some women perceive movements less than others. This may be due to the position of the placenta. A more concerning scenario would be if the baby moved a certain amount all the time and suddenly stopped moving. You should talk to your doctor immediately if something like that happened.

Yes: An ultrasound done in the first trimester will be accurate to within a week of the due date. In fact don't think of it as a due date, but more as a due week as 90% of women will have their baby one week around their due date. Ultrasounds in the second and third trimester will be accurate to within 2-3 weeks of the due date.

Which ultrasound results suggest a miscarriage?

Dr. Parul Krishnamurthy
Obstetrics and Gynecology 34 years experience
Empty sac,no beat: Miscarriage on ultrasound is determined if a pregnancy sac is evident but no fetal pole is seen or there is a fetal pole but no fetal heart rate is seen. Absence of fetal pole, could be due to the pregnancy being extremely early, then a follow up ultrasound is advised in 1-2 weeks. At all times unless an intrauterine viable fetus is detected, an ectopic pregnancy is in the differential diagnosis.

Low fetal health: A decrease in fetal well-being can happen for several reasons. Fetal distress can occur during the pregnancy or during labor. The warning signs are a decrease in the usual daily level of movement, greenish material present in a sample of the amniotic fluid, a decrease in the heart beats on routine check or during a labor contraction.
