When Should The Fetal Pole And Heartbeat Get Detected During Pregnancy?
Hello Doctor,
I am 7 weeks pregnant although when did an u/s scan it came out as 5-6 weeks of pregnancy.(My periods are normal 27-28 days cycle). There was no fetal pole and heartbeat but a gestational , yolk sac is seen. Doctor has advised scan after 10 days and said this will be the max waiting time for a fetal heartbeat. I am advised to take hormonal tablets (Conest). I am very much worried and really hoping the best for my baby. Can you please tell me how much possibility is there for a fetal heartbeat and fetaql pole after 10 days. Thanks in advance.

Hallow Dear,
Usually by 6 weeks or so the foetal pole and foetal cardiac activity is detectable by ultrasound. If by 7 weeks, it is undetectable, there are following possibilities:
1. The ovulation and conception might have occurred late in the menstrual cycle, which otherwise happens 14 days before the next menstrual period.
2. There could be mistake in calculating the duration of pregnancy.
3. The pregnancy could be without embryo (baby). This is known as blighted ovum. In such case, the ultrasonography image shows corrugated margins of the sac.
If the margins of the sac are well rounded, in order to exclude the first two causes, it is a good option to repeat the scan after a week to 10 days. If still the sac is empty, then the diagnosis of blighted ovum is confirmed.
However, if the edges are corrugated, it is blighted ovum. Pregnancies with blighted ovum do not grow. If such pregnancy does not abort spontaneously, termination is the requirement.
I hope this helps you.
