I have been having an upset stomach and cramps for a while (since ten) and before it used to come and go. But now it's more often, like it comes every ten minutes, and it lasts longer too. It hurts really bad now, and I can't sleep. I felt like a "pop" in my stomach too, kind of, and there was clear discharge from my vagina. I'm really worried. Please help!:( Here ten is different then your times- that would be six hours ago.
