TTC for 22 months now...

I've never posted on this, but I feel like sharing some thoughts.
My husband and I both got tested early this year and we are perfectly fine and fertile. We both have extremely healthy diets, we take our vitamins and get enough sleep.
Part of me wants to let go and see what happens. Part of me wants to keep checking dates and ovulation (just incase this is the month).
 Feeling low and puzzled as to why we are not getting pregnant.
