Am I not ovulating this month?

Hello ladies so I this month I haven't got a close to a positive opk all of them are very very faint lines. I started testing at CD 10 glow says I'm supposed to ovulate on Monday! But I haven't received not even close to a positive opk! If my CD is 30 days long then I'll get a positive on the 14th and if it's CD 29 days long then I should get a positive on the 13th right? I stop bbt because it was getting hard! *THIS WHOLE MONTH I HAVEN'T GOTTEN ANY EWCM 😩 I am taking the dollar store opks so I don't know if that has something to do with it
