Gestational Sac: The gestational sac is the first ultrasound sign of pregnancy. You will usually see it beginning 5 weeks from your last menstrual period. By 6 weeks you should see the yolk sac and by 6 and 1/2 to 7 weeks the embryo.

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.

What does it mean if my baby is measuring big for gestational age?

Depends: The average woman is around 5 ft. 3 in tall. If you had two women, one who was 5 ft 10 in tall and another one who was 4ft 11 in tall, you would not say either of these women are abnormal, just outside the average. So a baby that measure big for gestational age is outside the average. What you need to know is by how much is the baby outside the range of average.

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.

What is fetal distress?

Dr. Cassandra Ndiforchu
Obstetrics and Gynecology 49 years experience
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.

Absent normal heart rate variation during labor could also be a sign, as well as persistent fetal tachycardia.

Hydrops.: Fetal pericardial effusions can lead to tamponade and worsening heart failure with hydrops and fetal loss. Depending on their cause they may be amenable to fetal interventions and/or early delivery at a tertiary care center.
