[fin_xo]

All day today i have felt sick, close to throw up sick. That kind of light headed in the back of the throat sickness. I have eaten and drank water today so i know that isnt a problem, but i feel so uneasy and its freaking me out. I know that it is not in any way at all anything to do with pregnany..for sure. I know i havnt given muh detail but its like that feeling when you could throw up but wont. Help?? please
