Sorry for the delay in the response. If you were my patient, I would recommend that you go ahead and take the medication. Common name is Provera. Because you have a polyp, your doctor may want to do a hysteroscopy/d&c procedure for you to clean out the lining of the uterus. This procedure will be easier if the Provera has worked first.
If you were my patient, I would tell you to take your medicine, and then schedule the d&c for the week after the period that results from taking the Provera. I would probably just elect to watch the ovarian cyst, depending upon its characteristics--usually they go away on their own within 4-6 weeks.
Another option would be to wait on surgery, and just repeat the ultrasound in 6-8 weeks.
Be sure to discuss all of the above with your doctor!
Hope this helps!
