Big fat negative

My AF is due on the 12th and I tested today, just awhile ago and it was a big negative. I thought I saw another line but nope, I broke the thing open and nada. 😧😧 maybe it's still early, I've been having little cramps and severe lower back pain; I for sure thought I had it down this month. I guess we will see.. just a little rant. I'm still hoping, I have a lot of clear mucus when I'm usually drying up by now.
