Pregnant??

Erika
So the very first pregnancy test I took is the one I have posted on here, which to me appears to be positive. I proceeded to take two more over the course of 24 hours or so after taking the first- both were negative. Is it possible to get a false positive pregnancy test if you followed the directions completely? I'm not on any type of hormones that might alter my results. I'm over a week late already, and my cycle is very regular. What do you all think?! I'm getting a blood test this afternoon but am seriously so impatient and want to know for sure if I am!!
