I have terrible bloating. It starts just under my bust and goes all the way down. I'm on day 5 of my cycle and this started on day 1. Only had it once before like this and ot was 6 months ago. The doctor said it was likely IBS and gave me mebeverine. The bloating and pain has been terrible. My bowel movements have been normal although a little more frequent. Does this sound like IBS? Does pain and bloating with IBS occur so high up? My mind is in overdrive.
