I started feeling sick to my stomach last night before bed, and have been feeling yucky all day today. It honestly feels like I feel with morning sickness, but I took a pregnancy test, and it was negative (plus we used protection, and my period was too weeks ago, so I wouldn't think I'd be pregnant). I didn't eat anything weird & don't have diarrhea or cramps or other symptoms other than a sore throat from a cold that I think is coming on slowly.

Any ideas what else it could be?

Thanks....
