bloody mucousy stools, distended stomach, irregular BM, HELP!

I've been having BM issues for the past couple of years. I started having bloody, mucousy stools when I became pregnant, last January. It lasted throughout my entire pregnancy, but I figured it was just hemmoroids. All of the symtoms subsided for a few months, but have returned about 2 months ago:
2-4 BM/day---some diarrhea, some soft stools,
horrible sufar smelling gas
cramping in abdomen
distended abdomen
very bloody stools, sometimes mucousy
The doctor said I have no hemmoroids/fissures and that the blood is mixed in with my stool.
Does this sound like IBS/Chrones, or possibly Celiacs disease?
I also have pretty bad bruising on my legs and other symptoms (common of Celiacs) but they could just be coincidental
ANY IDEAS?
thanks!
