When to test after mc

L.a
Hi everyone tomorrow will be a month to the day that I miscarried. My husband and I decided not to wait for my next AF to show and kept trying. 
Do you have any suggestions on the time frame in which I should test? 
It was a early miscarriage at 5w4d.
I am experiencing breast tenderness especially centered around the nipple, some cramping but intermittent (which happens on my last pregnancy), decreased appetite, and exhausted (but I work over fifty hours a week plus going for my masters). 
Thanks to all who respond!
