Colonoscopy, CT scan, and now an ultrasound?

Long story short, pretty positive I have a mild case of Crohn's. Mom has it, I have the exact same symptoms as she does.

Trying to get diagnosed. I have had a colonoscopy with biopsies taken (haven't heard results yet), a CT scan last week, and this morning my family doctor called about a ultrasound?? Does sound normal or familiar to anyone?

I'm getting really fed up with all this. I just want to know what is happening. If anyone could give me any insight or thoughts(no matter how crazy) of what the heck is going on?

Thanks
