Digital says negative

want a rainbow baby
My first day of my lmp was 04/28. I was due for my period 06/01. I've taken digital tests and all day BFN. Abt 2 wks ago I started to get the symptoms of starting and got diagnosed with shingles (doctor negative tests were BFN) and the sores have nearly cleared up but still haven't got my period. What would you do?
