There's an article on the CCFA webpage (link below, the article is the 6th one down) titled "Management of the Pregnant IBD Patient" that has lots of good info about meds and their safety during pregnancy and breastfeeding.
Symptoms began in November 2008, ~4 weeks after giving birth to my son.
Eased for ~3 weeks in December, possibly b/c of probiotic use?
Returned in January 2009 (with a vengeance), diagnosed with pancolitis on January 30.
Currently taking Asacol (400mg 4 pills 3x daily), Rowasa nightly, Culturelle probiotic, and Zoloft (25 mg).
