I have read alot of stuff on taking Pentasa during Pregnancy, but has anyone had good/bad experiences? I am 5 1/2 months pregnant and came off my Pentasa because I was doing well before I became pregnant. My problem before was in the last part of the colon and many problems with fistulas. I now feel pressure in my inner thigh/panty line area and I am afraid I am getting another fistula. It feels swollen. Any advice on Pentasa and pregnancy would be greatly appreciated.
