Help please.... I’m so confused

I’m 6 DPO and started mild cramping yesterday/last night. I still have it today. Now that I’m 40 this isn’t uncommon for me to get this this far before AF is due on June 1. It usually happens every month. That said, we have been TTC for a while now, so I used to think it could be implantation cramps but month after month it’s just been AF doing this.

Does this mean this month it didn’t work too because I’m having the normal cramping I usually get before AF? If conception occurred would I not be having these cramps? If conception occurred implantation most likely hasn’t even happened yet right? Or is it that since I’m cramping like normal; conception didn’t take place? It messes with me so bad.

Any advice would be greatly appreciated ♥️
