HELP!! TMI

36w FTM...

So I dropped, and i was up all night last night with diarrhea and nausea. (Sorry tmi)... I'm having stomach cramps and they finally eased up but I ate again and now they're back and I can't get off the toilet. I've also been soooo restless and I can't get comfortable at all. I'm leaking from my boobs too and there's lots of pressure now. Is this normal?? If this happened to you when did you go into labor?
