Normal blood tests are a good thing, but they don't mean you aren't sick. They show that you aren't anemic from the bleeding, aren't developing liver problems that sometimes go with IBD, and that's very positive. If your blood-making system keeps up with your bleeding, you don't get anemic. If not, you might need iron supplements or even transfusion.
If you really feel that your GI thinks you're not as sick as you are, consider another GI. My first one thought because I wasn't losing weight I wasn't that sick. I guess because of that he didn't believe I was going 20-25 times a day, in a lot of pain and barely able to drag myself through the day at work. I changed and found a wonderful doctor who totally believes me and was as frustrated as I that I was so sick from "just" left-sided UC.
I hope you feel better soon, butterfly.
Left-sided UC diagnosed 2001. Taking Colazal and Imuran, Remicade infusions and moving into remission. Finally off steroids after four years!
Now in remission for almost two years. Remicade has been my wonder drug.
