I've had my period (spotting) for almost two months now after not having it for 2-3 months, what should i do? what could be wrong? it's painful, help.

Irregular periods: Irregular periods are one of the most common problems obgyns treat. If this is one time problem it usually resolves on its own. If this is a recurring problem you should be evaluated. Infections & hormonal changes can cause spotting. If there is a concern for pregnancy then do a home pregnancy test . There are many options available to help regulate the menstrual cycle. Schedule a visit.

See GYN: You need some blood work and likely a medication called provera (medroxyprogesterone) for 10 days. The spotting isn't your period. Its likely breakthrough bleeding from not having your period. This could eventually lead to severe bleeding, so if you don't have a gynecologist at least call your family doctor and start there.
