Could i be pregnant?

Mrs

It's 2 days before my period and I took a pregnancy test and it was negative. I've been feeling nauseous all the time and hungry. Some foods sound good and some just sound gross. I've been dizzy and have had some cramps and tender breasts. I've noticed that I've had indigestion after meals as well. I've never felt nauseous all the time like this before. Do you think I'm pregnant? Does this sound like anything you experienced?
