Pain and infertility are the most common symptoms. In women who are able to conceive, symptoms may get better during pregnancy, but they may return after having the baby.
Here are other symptoms:
Irregular periods. In 15%-20% of cases there is premenstrual spotting.
Periods that are unusually heavy, especially if they produce large clots and last more than seven days.
Pain that gets worse during your period.
