Bleeding??

Amber
I feel like I'm gonna lose my mind.
I took three pregnancy tests over the course of the last three days, all positive. Light, but positive. And all the sudden yesterday I start bleeding, red and period like. 
So, I went to see my OB.
They said the pregnancy test they did in the office was negative and that I was either getting false positives or having an early miscarriage. Now I'm sitting here waiting for blood work to tell me what's going on. Has anyone else been through this and things been ok? I'm freaking out...
