I'm 34 and 4 years ago I had all the tests for ovarian cancer it was negative. I now have all the symptoms, could I be in the late stages of it now?

You can not be so su. If you have symptoms, then an examination by your doctor is the first step. Only if he/she suspect something on an examination will they order imaging studies with an ultrasonogram or ct scans which can easily show the status of your ovaries. I would not get so anxious right away when your previous testing has been unremarkable. It may simply be fear/ worry of the unknown. Your doctor can help.
Ovarian tumor. A follow up with your ob/gyn doctor will clarify the issue. Wish u well.
