I am the CL of the Ovarian Cyst forum and you definitely sound like you may be suffering from cysts. Please ask for a transvaginal ultrasound and come on over and visit us.
It would be better to get a colonoscopy for your condition, basically a camera from the other end.
My cousin had a similar condition recently and it was actually small cysts on the ovaries, they were burnt off by laser and now the bloating has gone, the pressure may be affecting you digestion, but i would get both checked out.
