Thanks for posting your query.
From the Ultrasound
reports, your baby is growing normally. The average Crown Rump Length (CRL) for 8 weeks gestation is 1.6 cm. Your values are normal. The fetal heart rate
is also within the normal range of 110 to 180 beats per minute.
Sometimes ovarian cysts are discovered by ultrasound during pregnancy
. They are usually benign and do not require any surgery. Cysts below 5 cm diameter usually do not cause any complications.
Though there is the rare possibility of rupture or torsion of the cyst. By and large ovarian cysts dissolve on their own.
If the cyst seems to be increasing rapidly in size at the next scan (an unlikely event), then please discuss with your doctor about possible laparoscopic methods of removal.
As of now nothing needs to be done.
Wishing you good health.
