Hi Lalee -
No the Pentasa will not affect your birth control. And yes, many women find they are even more miserable with their Crohns during their monthly cycle. Also, I took the birth control pill for probably 10+ years, and they really helped to make that monthly time much more manageable. In fact I ended up getting a hysterectomy after I went off the pill, because life was so much more miserable without the BC pill. (I had already had my children at this point and wanted no more). Hope that helps.
