Good Morning! I am 5 weeks today and I also have IBS. I have noticed that anytime I have a bowel movement I get horrible period-like like cramps afterwards. they go away after 5 minutes and I am not spotting. My BM are looser than normal but not complete diarrea. Should I call the doctor today and inquire. Do you think it could lead to miscarriage? If you have IBS and are pregnant or had it during, please advise. I have the diarrea side of IBS.
