Menopause or what

I am 51 and had a d & c for excessive bleeding, and pain from endometrious(sp) 17 days ago.  I also had a recurring uti since July.They removed a couple of fibroids and polyps, which came back benign.  They did a laparoscopy and hysteroscopy along with the d & c.  Symptoms of uti are now gone but I have been bleeding since 5 days before the surgery, heavy at times with clotting and back pain and cramps.  They were also going to do the novasure ablation but the doctor said he tried twice and could not do it because my uterus was misshapen.  The doctor had me taking Megestrol 20mg twice a day for a month before the surgery to control the bleeding and has now increased it to 40mg twice a day for the last few days.  It has not stopped or slowed the bleeding yet, whereas when I first went on it, it stopped it for a month until 5 days prior to surgery and then it was only spotting.  Now it is heavier again.  He mentioned trying Zoladex if the Megestrol didn't work, and if that didn't work, then a hysterectomy.  Up until now, I have had regular periods and he said a couple of months ago, my hormone level suggested a couple more years of menopause.  Now he said a couple of months on zoladex might get me through menopause.  Am I missing something, or is there something else to look at?
