Should I stop rowasa?

I have been on the enemas for about 3 wks. I stopped bleeding after about 3 or 4 days on them, still had some problems in the mornings with cramping and spending a good amount of time on the toilet. I missed one night of the enemas and the next day had blood again, I have been using them faithfully everynight and now I am having more blood along with a lot of mucus, also my frequency seems to be increasing,  I now have to run to the bathroom a few times in the afternoon and evening and its usually just mucus with a bit of blood mixed in. I am just so frustrated and aggrivated, I am getting very depressed. just feel like nothing is working. I am also 9wks pregnant and do not want to have to go the next step of meds, ie. 6mp. Any help or suggestions would be appreciated.

Thanks again.

I was wondering about asking for asacol but thought it was pretty much the same as colozal so I figured it wouldn't matter. I did try using the ginger gum but honestly it did not help at all so I don't bother. I did end up talking with my GI and he wants to order stool tests because I did have c.diff recently so I think maybe he is concerned about that again. I do have probiotics at home but didn't really notice much of a difference when I used them so I just stopped. I have never tried fibre supplement because I was always worried they would just make things more loose which I def. don't need.

Thanks,
