I am experiencing irregular menstrual periods.

Lots: there can be lots of things causing this

Irregular: IF this has been going on a awhile then, I would see a gynecologist or your family doctor.

Irregular periods: Irregular clothing sizes often lead to markdowns in retail stores. However, irregular periods are the bane of a woman's existence as the unpredictability makes it difficult to not only be prepared for the flow, but raise concerns about pregnancy if sexually active. You need to see a GYN MD to be evaluated for the many medical causes for irregular periods and a solution with Rx.

See a doctor: I am sorry to hear this. I would recommend seeing a doctor to go through your history, have an exam and possibly an ultrasound and blood work. Good luck.
