extreme pain post m/c

I've already got an appointment to see the doctor tomorrow, but I was wondering if anyone else experienced severe cramping post miscarriage?
I used cytotec, and passed the sac on Saturday morning. Saturday and Sunday I was okay, but Monday night out of the blue, I started cramping. It steadily got worse until, on a scale of 1-10, I would put it at a 9 (with a 10 being just before I passed the sac). I took ibuprofen and naproxen, took a hot shower, and then went to bed with my heating pad. Curled up in the fetal position and sobbed. About an hour later it finally eased up and I fell asleep.
Tuesday started out okay. I went to work for 7, and was fine for the first few hours. Around 10:30, I started cramping a little bit, along with nausea and heartburn, but it was manageable. Around 4:30 is when it really hit me. I managed to choke down my dinner, then I went and curled up on one of my residents beds in a tight ball and sobbed.I ended up spending the last two hours of my shift curled into a ball because I couldn't move for the pain (luckily I could just be a body at that point).
Today, I spent the day doing nothing with my bff, literally just laying on her couch watching movies. Again, I was fine when I first got up, but as the day progressed, the pain got worse. My husband asked me to pick up some groceries on the way home, and I managed to get about a third of what I had planned before the pain became too much. When I got home, I passed a sizeable clot that was fairly solid and looked like it had tissue attached. Passing that didn't really help with the pain.
I'm fairly certain that this is not normal, and I can't seem to find anything on post miscarriage pain online, which is why I turn to you.
