See if you can change to Asacol...that might help with some of the nausea.
As well..maybe try fibre supplements and probiotics.
Just an aside..careful with ginger for nausea since you're pregnant..don't know if you've used it, just that I've read it's contraindicated in pregnancy.
*Heather* I give suggestions, do with them what you will.

My doc's logic.. "TREAT (FROM)BOTH ENDS" worth it !!!
