Opk advice?

Chelsea

I’m new to using OPK’s and need some advice...

I got a positive last night and we BD twice....

I tested again today and it got fainter - which I think is right? 😬

Can someone just explain to me -

1) are you supposed to not test again after that positive?

2) if so, do you start testing again after AF shows (if the witch does)?

& 3) if I tested positive yesterday, do I count today as 1dpo?

Thank you everyone xxx
