Completely bummed.

I just dont understand. We have been trying for 2 years now. This month, we did the deed every other day, used preseed, tracked temps, did opks, and still nothing. AF is due in 2 days. Feeling like it's not meant to be for us for some reason. Drs have said everything is fine for the both of us, I'm just over it 😭

Could someone tweak for me for piece of mind? TIA.
