When to start using OPKs after Clomid?

[tuba]

Hello
I've decided to take Clomid without prescription only to help with swaying pink. I took it from CD 3-7. Today is CD 9. My question is when should I start using OPKs?
My cycle is 30-35 days, does that affect the ovulation with the use of Clomid?

You can get false positives on OPK for 3 days after your last dose, so start OPK 4 days after your last dose. The earliest you can O is 5 days after your last dose, so this works out nicely.

Clomid can change your O day and your cycle length. The length of your cycle doens't have any effect on that, it can change even if you have a 28 day cycle!

I can't thank you enough, Atomic. I learned a lot from you.
