Feeling Nauseous all day!

Leeann
So I've been off my period for a week now and I feel so nauseous. I've been feeling this way since I started my period so it's been two weeks now. I took a pregnancy test a day before my period and the results came back negative. EVERYTHING I eat has a weird nasty taste to it even water. The thought of eating meat makes me sick. Certain smells makes me nauseous. I want to take another pregnancy test but I don't want another negative result. What do you all think? Should I take another pregnancy test or just wait until I miss my period?
