Hi, my name is Tammy, I'm 36 week's and 2 day's pregnant, and a few hours ago I felt really crappy, it started with feeling dizzy off and on all day, then a headache, then I started feeling sick like I was going to puke, then I started shaking, it lasted about 2 hours, give or take, after a while I took a poop (sorry for too much information) and it was loose, but not diareah, which is weird because before today I have been constipated, so I guess my question is could this be a sign that labor is near, or is it normal?
