What Causes Heavy Periods After The Removal Of Ovary?

Hi, I m 48. At age 43 I had my left ovary removed because of a cyst and was diagnosed with 5 fibroids in my uterine wall and uterine polyps (nothing cancerous found during surgery for ovary removal in 2010 or polyp removal in Feb. 2013 ). I never had heavy periods until after my ovary was removed, now I have heavy periods that usually last 10 days sometime longer. Last month, a week before it was due, I started bleeding and it was brown and very light and lasted 5 days, I had some cramping in my back and my left side. I did not have a regular period. I missed my period again this month, I m not having unprotected sex and I ve never had children (I wanted to at age 43 this is why my doctor was reluctant to do a hysterectomy). I ve been poked and prodded so much during the last 3 1/2 years I dread going to the doctor. I m hoping- could this be menopause?
