Is there any reason that IBS-D would start up after a pregnancy? I always had symptoms around the time of my period and stress, but not as a general occurrence. I had never previously labeled it as IBS-d.......it just seems to fit the symptoms I've always had.I had my dd in September and am breastfeeding, with no AF yet. For the last (weeks?? maybe months??) my symptoms have been consistent, day-in and day-out. I kept thinking that I was getting AF back, until I realized that it had been going on for a while and AF had not returned.My symptoms are diarrhea that is urgent, cramping, gassy cramps, stinky gas all of the time. I dread having this conversation with a doctor.
