Am I out this month or?

V

I’m currently 3-4 days from af and I’m 11 dpo. I tested this morning with fmu and got a bfn. Today, my lower back has started aching, I have some slight cramping/twinges, and I’m crying at the drop of a hat. I’m worried it’s af beginning to make her approach. What do you guys think? Am I probably out this month or do I still have hope?
