At what CD do you start OPK?

[Lemacy]

Hello ladies!

I am CD 10 and am thinking about starting my OPKs today. Last cycle I started on CD 11 and got a + on CD 14. I don't want to waste them but at the same time I want to see a big enough window to get a good idea of when I OV each month.

So, when do you start your OPKs and why?

TIA
