My wife examined and had an ultrasound, the doctor concluded as follows: The bottom of the uterus has the shape of a gestational sac, even edges, and a live fetus inside. CDĐM (CRL) = 4mm, positive fetal heart. Right ovary: There is an empty Echo structure measuring 67*56mm, the left ovary is normal. Result: A live fetus in the uterus for 6 weeks, a simple cyst in the right ovary. Doctor, can you tell me if a 6-week pregnancy with a simple ovarian cyst is dangerous? What is the treatment direction so as not to affect the mother and baby? Thank you, doctor.

Doctor, is a unilateral ovarian cyst dangerous? Does the treatment of this cyst affect fertility?
