Pregnant or not??!!

A
So I started having cramps a couple days before my period and then I had terrible cramps and I only got some dark colored spotting. I've had some cramps and fatigue since I stopped spotting. I took a pregnancy test and it said negative but it was an evening pee. I'm going to wait a week and take another test but I'm so nervous. Is there any other symptoms I would have if I was pregnant this early?
