now what?

I've been having pelvic/abdominal back pain for about 6 weeks, pressure and bloating.  I am not constipated, but have noticed changes in my bowel habits.  going 3 or 4 times a day totally not normal.  I went to the doctor.  She thought I had a cyst on my left ovary, so they did a transvaginal ultrasound and a ab and pelvic ct.  Both tests revealed 3 small fibroids and nothing else.  My gyn said those are too small to cause my discomfort.  I guess the only thing left is something wrong with the colon.  My question is, would a ct reveal colorectal cancer?  Or do I need to have a colonoscopy?  Would a barium enema be right?  I am worried and confused and my doctor is out of thwn this week!  HELP!!

Hi There,
a ct scan does not replace a colonoscopy. A CT scan would show if there was a big abnormality in the colon. So if it is normal, you may just have irritable bowel which can be very uncomfortable
