The anticipation is killing me!!!

I took a pregnancy test yesterday and the day before, both negative. My period isn't due till Thursday, but I've been feeling dizzy and had a couple of barely visible drops of blood yesterday (implantation bleeding?). No major symptoms if pregnancy or period, which makes me so confused. I go to obgyn tomorrow for annual. Are their tests better than home ones? We've only been trying for 4 months, but I just wish it would happen already!!! It's all I think about! Any feedback is appreciated!
