What in the world is going on? lol

So I have been TTC since my m/c on 3/18/15 and I am now 10dpo but I took a test about ten minutes ago and got a BFN. I'm due for AF on the 19 and I feel a lot of pressure above my lady parts! (Feels like a water balloon is sitting on top of my pelvis Lol) im also having mild cramps but not like period cramps just weird little faint ones. I experienced none of this during my last pregnancy. Has anyone else felt this did I test too early?
