bbt chart help- no ovulation?

M • UK. TTC Baby#1 . Partner Low Sperm Count. Polycystic Ovaries.

i got my peak on clearblue advance digital on 27th June CD19 but still havent ovulated yet right?

Do i need to keep testing now with my opks? I put them away as i assumed i would ovulate.

This is my chart from last months cycle.

Any suggestions please?
