Diverticulitis and spotting?

im awaiting diagnoses of possible diverticulitis, been told it may take a few weeks for a ct scan, im in the middle of the antibiotics and starting to improve,,part of the reason why its taken so long to get help is that they thought it was something gyne due to spotting and bleeding between periods and most of the pain was low in the pelvis on the right,,they thought it might be an ovarian cyst at 1st,,urghh its not been very nice but at least we are getting closer to having answers,,,any help or advice would be gratefully appreciated,,,,i had read that diverticulitis mainly presented with pain on the left,,???
