After having a hydatidiform mole, how long should I wait before trying to become pregnant again?

Women should wait 6-12 months after treatment for a hydatidiform mole before trying to become pregnant again. This allows time for testing on the tissue that was removed. This also allows time to make sure there is no remaining tissue that could turn into cancer. The molar pregnancy could recur if pregnancy occurs too soon after treatment. Talk to your doctor to determine the best time to attempt another pregnancy.
