Ovulation approaching?

Lauren • Mummy to Kameron & Emilie 😘
I know it's not a positive but for some reason these days Clearblue don't seem to work for me. I'm using the fertility monitor with fmu but no high yet and I'm roughly on cd 13 out of a 30 day cycle. I don't chart, wouldn't know where to begin lol. 
​With fmu I don't seem to get good lines. Works better for me with a short hold of about an hour and usually about 11ish 
​I have pcos and i had been getting positive ovulation tests at about cd 23 so I upped my dose to 1000mg in the hope it will help me ovulate earlier. 
​These are my tests from today with fmu and 2nd mu
