Still hope? Pleaseeee any advice

I'm supposedly 22 dpo and have non of the normal symptoms I get with PMS and I'm currently 8 days late. I usually get really bad cramps and sore boobs the few days before AF but so far I've had nothing besides being absolutely exhausted and moody. I've taken 3 tests and all have been BFN. This is our 7th or 8th (I quit counting) month of TTC. Please does anyone have any advice? What should I do? I hate the waiting game I wish I would either get a BPN or AF would show. HELPPPP
