Helpppp.

I have a question, I have never been irregular until like September. I missed af the whole month finally came on Oct. 5th, this month I’m already late and all negative test. My question is when should I start taken opk’s? I have attached my Ovia calendar from last month and this month. I didn’t track ovulation last month because everything was so messed up I’ve never had that before. Ovia is not even giving me an ovulation period like it normally would?

Thanks in advance for the help.
