If there is an ovarian cyst and at the same time it is found to be pregnant, the effect on the fetus is not significant. It is recommended to first rule out whether the cyst is caused by a physiological cyst, because after ovulation the corpus luteum is formed, which may also be seen clinically through ultrasound examination. If it is a pathological cyst, it is recommended that in addition to regular check-ups during pregnancy, it is also recommended that a cesarean section be performed at full term to remove the ovarian cyst. In addition, the cysts have little effect on pregnancy during pregnancy and regular checkups are recommended. However, if acute lower abdominal pain occurs, it may be caused by torsion of the cyst and requires surgery.
