I've suffered for years with Ulcerative Colitis which developed into a general IBS. Since coming off the pill 2 years ago, the IBS symptoms have got worse and worse, to the point that I was having the runs most days.
I have always been aware that the IBS was worse around my period - but in the last few months I noticed small blood clots in my stools, and bleeding from my bowels at the same time as my period. I don't get this bleeding at any other time of the month.
A few months ago, I experienced a searing pain in my abdomen - right around where my appendix is. I collapsed, vomited, and had to call my DP to come home and pick me up off the floor. By the time I got to the GP later that day, the pain had subsided, and they decided it wasn't appendicitis because it didn't hurt when they pressed it.
Since then, I've had no serious pain, but do get niggling abdominal pains from time to time. I do also get serious period pains for the first day or two. The serious pain episode happened during my period, but a few days after the usual period pains have normally gone away.
My GP has now referred me to the gastroenterologist for investigations (pipe up the bum, not a camera.. TMI?) to have a look at my bowel and look for a possible cause. She thinks it's either a return of the colitis, or Endo.
Because of the period related bleeding, and the pain episode - I'm convinced it's Endo - which upsets me as I'm TTC 
Anything I need to ask / should be prepared for tomorrow?
