I have had my ileostomy for nearly 12 years, and I agree with your symptoms of a pain similar to a pain in the ovary. I went to the doctor, had tests, etc., and they found nothing wrong in my large colon but diverticulitis. So, a gastroenterologist told me that the large colon is still alive in our bodies and has blood flow, and so secretions get caught up in the sacs. When they get full, they have to get the stuff out, and that's when we get a rectal discharge, and the pain usually stops. I had never had it in a large dose that looked to me like baby poo until a year ago, and I went into a panic. Always before, it was a bloody discharge and little grey things about the size of my fingernail. It sometimes takes a day or two to finally all get out and back to the clear liquid that is always there. I also have learned to not eat past 2:30 PM or latest 3 PM, and then I have a small snack before bed (for me about 11:30 PM) and sleep until 8:30ish, and I don't have to get up in the night to empty my bag. Most of it is out by 11:30. Now I have sugar-free candy I suck on, and I still drink my coffee during the evening. I do live alone, and I'm 84 years old, so I don't have to fix an evening meal for anyone. It does make it easier. Don't worry about the discharge like I did. Nobody ever really explains anything to us, do they? Also, after you pass stuff, the pain goes away too, doesn't it?
