If a right-sided ovarian cyst is found at the time of examination in early pregnancy, the specific treatment needs to be decided based on the exact size and nature of the ovarian cyst and whether there are symptoms. If the ovarian cyst is relatively small, <5cm, and it occurs and develops slowly, grows very slowly, and has no symptoms, it can be followed and observed. However, if the ovarian cyst is larger than 5 cm, or if it is growing rapidly, and if there are symptoms of hidden pain in the abdomen, it is recommended to remove the ovarian cyst at 14-16 weeks of pregnancy, if it is clear that the ovarian cyst is benign, so as to avoid rupture of the ovary or torsion of the ovarian cyst due to the enlarged uterus pressing on the ovary in the middle and late stages of pregnancy.
