1st time OPKs user here

Happy New Year every Glower! 🍾

I’m looking for any words of wisdom, advice or thoughts for a first time user of ovulation tests.

I just received 50 ovulation strips and hoping you can help me with them. How should I start off?

Glow predicts my fertile window to be January 3-9 (the 8th as my peak day). I’m on CD 11 today and I took a dollar store ovulation test and it was negative. When should I start?

Any pointers or shared experiences is appreciated! I’m on cycle #3 for baby #1... it’ll be our second month with Preseed as well.

Thanks!!
