Help...

Updated: To show my full chart. bbt in the beginning is crazy due to me not taking it first thing in the AM.

I stopped LH tracking due to my period supposed to come. but according to this app I am 6 days late. My glow app that I've used for months says I'm 2 days late and that one is usually spot on. I took a HCG test yesterday morning and came up Neg. This is the 2nd cycle in a row that I've been late. My DR said my blood work is normal and there is nothing concerning. I haven't gotten a Peak LH reading in this cycle. But my Cervix as of yesterday was high, slightly open and soft. I did feel some nausea last night. and couldn't sleep. Any ideas? #ttc
