7 Days late.....Nothing, Anyone else?

Kaila
Hi everyone, 
So I'm dying to know. The wait is killing me and I can't seem to get a BFP. I've taken tests on the 3rd and 4th day after AF was due. And then I took one on the 6th and again on the 7th day. This is very much wanted and I'd just like some advice or something, to soothe my nerves. Could I actually be pregnant? My AF is never late. If anything, it's a day early. Help??
