Ovarian cysts are a fairly common gynecological disease in women of any age, and can be common during pregnancy. Many women only discover they have ovarian cysts during a pregnancy check-up. Most ovarian cysts are harmless and there is nothing to worry about.

Corpus luteum cysts are a fairly common condition in women. This condition is usually not a cause for concern, but it can worsen and affect the health of the mother and fetus.

Ovarian cysts in pregnancy are often diagnosed incidentally through fetal ultrasound. Pregnant women can have any type of cyst, but the most common is the corpus luteum cyst, rarely malignant cysts that are dangerous to the mother and fetus.
