Had 2 Polyps Removed From Womb, Mild Indigestion, Increase In Bowel Movements, Frequent Urge To Urinate. Ovarian Cancer?

I had 2 polyps removed from my womb in the summer of 2008. They were benign. I now seem (not sure) to be getting the signs of ovarian cancer i.e. mild indigestion, increase in bowel movements, frequent urge to urinate, lost half a stone in 3 months owing to reduction in appetite . What should I do? My doctor has given me a routine appointment with a urologist the third week of May (2013). Thanks.
