I m having this--discomfort in my left abdomen. It s not really painful, it s uncomfortable. A while back I was sick and coughed so bad that my ribs on the left side were sore. Now that soreness or tenderness is still there, but also my lower abdomen is having discomfort. Now, I missed my last period, and I feel odd. And no I m not pregnant. Also, right now I m having this--I feel like I can taste or smell a vomit scent but I don t feel like vomiting...
