Is it still possible?

I'm 31 and I'm hoping/praying! TTC #1. 23 DPO. took a test 5 days ago, expecting it to probably be too early, it was BFN. AF was due two days ago, took digital test today, another negative. My cycles are on and off. It might be in my head but I feel like I'm experiencing some symptoms that I don't normally have with AF, extreme bloating, daily headaches, gassy, tired. Is it still possible?
