How can I not be pregnant?

Abigail

2 days ago I had a very very faint line on my pregnancy test (11 DPO). My breasts were sore, I felt nauseous, I had mild back cramps, and I started spotting.

Yesterday i started bleeding heavy, less heavy than my period but more than what is described as implantation bleeding. I took another test and it was negative. If it was my period, I started 3 days early.

I'm still bleeding today, and had another negative test.

I feel different. I can't explain it, but I feel pregnant. I know that can't be possible. 2 negative tests and bleeding. But I'm still nauseous, having food cravings, cramping (which I usually only get on the first day of my period) and I'm beyond emotional.

I feel like I'm going crazy.
