I had an irregular shaped gestational sac. At 8 weeks I had a scan which showed that the yolk sac measured 8 weeks but the fetal pole only measured 6 weeks but there was a heart beat. I had a repeat scan 2 weeks later sadly to find that the sac had collapsed and no heart beat. I have to go for a D and C tomorrow because my body as not rejected the pregnancy.Thus in my case a irregular shaped gestational sac was not a good sign. I also had a slightly irregular shaped gestational sac first noticed at a 6 week scan with a heartbeat of 118. I had bleading with this pregnancy as well that started as a light discharge and then became a steady period. I went to the E.R. at 8 weeks and the baby's heartbeat was strong at 150. The E.R. doctor said they could not tell where the bleading was coming from, but noted again that the ultrasound showed a slightly irregular shaped gestational sac and to follow up in 1 week. Two days later, I miscarried at home. After talking to several friends that are OBGYNs, any irregularity to the gestational sac will most likely lead to a miscarriage.

Is there no hope for your baby if the gestational sac is irregular?

My understanding is that it depends on if there is a baby. Mostly if there is an irregular sac, it indicated that the baby is not developing within the sac - a condition known as blighted ovum. If this is so, then your pregnancy will definitely miscarry. BUT if you have an irregular sac, but the fetal pole and heartbeat are visible, there is a high chance the pregnancy will continue.

A single live fetal pole is referring to the baby in the stage when it is first visible inside the gestational sac. As for the intrauterine gestational sac, that is means the pregnancy is seen within the uterus and is not ectopic.

What does an empty amniotic sac mean?

What is a Blighted Ovum (Empty Gestational Sac)? A blighted ovum (empty gestational sac) occurs when a fertilized egg implants into the uterine wall, however, the fetus does not continue to develop past the sixth to eighth week of gestation. There is continued development of the placenta and amniotic sac which produces hCG (giving the positive pregnancy test). Most women either do not know they are pregnant or find out within the first trimester that they have a blighted ovum (empty gestational sac).

Is pregnancy normal if you've had an ultrasound at 3 wks and see no gestational sac?

At three weeks you have likely just implanted (assuming ovulation and conception at two weeks) and there would be no sac visible. According to some websites, it can be seen as early as 4 weeks. Personally speaking, I had an early ultrasound at 4 weeks and no sac was visible. A gestational sac and yolk sac were visible at 5.5 weeks.

Is it normal for an ultrasound at four weeks and four days to show only a gestational sac?

That sounds perfectly normal. The gestational sac is all that is able to be picked up at this stage. The baby grows within it. By the fifth week, the location of the baby becomes obvious as does the fetal heart.

Im 5 weeks pregnant and an early scan showed a gestational sac but no yolk sac yet-when does this appear?

Im 5 weeks and 2 days. The gestational sac is measuring 1.11cm I also have no yolk yet. Everything Im reading up on is saying there should be a yolk BEFORE the gestational sac measures 16mm in order for it to be considered a viable pregnancy. 10mm = 1 cm so Im like 12 mm now or so. It says on average the yolk appears when the gestational sac is between 8mm- 10mm. Ask your doctor what the sac is measuring. Maybe we are just really early. I did see a post where a girl said she had only a gestational sac 2 weeks ago. She was measuring 4 weeks 5 days. They rescanned her 2 weeks later, she had a fetal pole and heartbeat and it measuring 8 weeks and 2 days. So I suppose theres hope. Im trying not to get too discouraged yet. Good luck and you can email me at if you would like. Id love to hear how everything turns out.
