Two peaks on Clearblue digital advanced-need help

Hello everyone,

I took letrozole this cycle. I’ve been testing since CD 9, and I got peak on CD 17, and I was running out of ovulation tests so I bought one more box so I had an extra one. As once it peaks it stays for two days, I wanted to check if I was ovulating the next day with the new monitor, it it showed low fertility - ‘ O ‘ on CD 18, but yesterday it was peak again on CD19.

Can someone interpret it? Am I overthinking it too much? Based on my peak on CD19 my calendar changed my ‘Possible’ ovulation date. Which one should I go with?

Also with my pregmate ones the first line is less darker than the control one, so I still have not peaked yet right? PLEASE HELP!!!! I’m having hard time interpreting these!!
