10dpo

I folded and bought a cheapie test, I'm 10 dpo today, and I tested in the afternoon. It came up blatantly negative. I feel so depressed and I just don't understand. My breasts feel heavy and hurt so bad even just walking, I'm super bloated and emotional. I had extreme hot flashes and cramping on my left side 8-9 dpo, and  that's when my breasts started hurting. Did I test too early? Am I out?
