I think it to be normal.

Detailed Answer:
Thanks for asking on HealthcareMagic.

A normal fetal heart rate (FHR) usually ranges from 120 to 160 beats per minute although at about 7 weeks it is usually between 150 to 170 beats per minute. It is considered slow for this age only if it is below 120 per minute.

The rest of mentioned findings seem normal.

Brief Answer:
Periodic follow up is required

Detailed Answer:
Thanks for writing back.

There is a caution sign but that does not mean that you need to get anxious. You need to remain in proper follow up with your doctor. The USG needs to be repeated after a few weeks. Prenatal diagnostic procedures like amniocentesis with karyotyping might be required if the heart rate is still low by 14 weeks. It might be preceded shortly by Maternal serum screening including β-hCG, PAPP-A, alpha fetoprotein, inhibin-A.

The results will confirm if there is actually anything to worry about. Chances are that it is just a normal variation and not a cause of concern.

Stay relaxed. That is very important for a healthy pregnancy.
