Am I possibly getting close to Ovulation? Pic in comments

Kellie
Hi I have just started Metformin this cycle ttc #3 after trying for 2 years (last child was a clomid baby) I have Pcos and cycle lengths are all over the place (but last one was 33days) Ovulation tests don't work too well for me but these are the ones I have done this cycle.. Am I getting close? Is it a good sign... Currently cd16. Thanks in advance
