It's 2:30 am CST and I was woken up by intestinal pain. It's on both sides of my intestines at waist level. I'm taking a nulev as we speak, which will be followed by immodium, because even though nothing has happened yet, I know it will. I didn't eat anything bad today. I exercised a little bit at the Y in the pool. When I got hope I had menstrual type cramps, which I assumed were from swimming. Now this. I finished my menstrual cycle on the first. What's up with this? Why now? And why does it have to hurt so much?
