In most cases, an ovarian cyst during pregnancy is not concerning. The majority of ovarian cysts are painless, benign, and disappear on their own. Even though ovarian cysts rarely cause symptoms, they can be painful if they rupture.

When you are pregnant, sonograms may occasionally reveal an ovarian cyst of a different type than the one you had previously.

In fact, the majority of medical professionals advise watchful waiting as the preferred course of action for ruptured ovarian cysts during pregnancy (which entails observation, ultrasounds, and monitoring).
However, your doctor may recommend surgery if there is:
Not all women experience pain after an ovarian cyst ruptures, but some do when the rupture takes place. Symptoms of a ruptured ovarian cyst may include:
