what do you think? am I pregnant?

I took this this morning and it was a first response digital test. It said no, I read on line were a lady took hers apart and found out she was pregnant the line just wasn't that dark. I'm supposed to start my period in 3 days but I have been using the bathroom a lot. Also, I always have sings of my period at least a week before and this time none. What do y'all think?
