For the past week or so, I have been waking up during the night feeling so nauseous where two nights out of the past five I have actually vomited. One night I woke up and ran to the bathroom feeling as if I were getting ready to vomit, I prepared myself but nothing came out so I sat there for a little bit and tried to see if I had to empty the bowels, where I found myself to have diarrhea and after that episode I was fine and went back to sleep. The next night I woke up with another horrible nauseous feeling, but did not vomit. The same with the night after that, and even last night. I doubt it's the flu, because usually it's just a 24 hour bug. And I have also been experiencing cramping with the nausea, as if I were to get my period (which is supposed to be due this coming Friday, December 14th) and my ovulation was the 29th of November through the 4th of December..... I have noticed a drastic change in my eating habits too, I'm eating a lot more food as normal. Could I be pregnant?
