You didn't say if you are male or female. If female, I'd just get checked out by the GI to make sure all is well. I talked to mine and my PCP before trying. We adjusted my meds then started trying. It took a bit longer than I expected but in the normal range. Good luck to you.
Hoping to stay in remission after the birth of a healthy baby girl. On Pentasa during my pregnancy, went med-free 2 months to nurse (stupid), but back on Pentasa and still nursing.
