Idk what's going on with my body.

Dani • 21- married over a year/ but I`ve been with my husband for 5 years. Currently ttc. Using OPK`s & waiting to try preseed.
As of march I took out my nuva ring. My husband & I are mostly Ntnp . Since March my periods have been on time & my cycles have wen regular.  I've been tracking everything. July 19 my period was due & I still haven't gotten it. 
​I've taken tests, went to the doctor - took their test & a blood test. My apps don't even know what to do for charting because they all seem to be assuming my period will come "tomorrow". 
​I've been taking ovulation tests & all have been negative. Idk what my
​body is doing right now & the do tors don't either.  
​Has this happened to anyone?
