Testing with OPKs

Stephanie

Hi ladies! TTC newbie here!! Just have a few questions, hoping some of you ladies could answer them for me!

1.) do you start using OPKs the first day after your period ends?

2.) does it matter the time of day to test using OPKs?

3.) when do you start testing 2xday?

Any and all info will greatly be appreciated! Thank you!!
