CD19 and still no ovulation

This is the first month I have tracked everyday with my opks. I'm at cycle 19 and still haven't gotten a positive. I'm a little concerned. Usually my cycle is around 28-30 before my iud and during my iud when I was getting my periods. Took iud out 2 months ago.

They look close for so many days but haven't gotten a positive one. This is so frustrating!
