When to test OPK

Question

I have a 28 day cycle almost religiously. My period ended last night. When should I start OPK testing?

Answer

You start CD8 or CD10 depending on average length of your cycle. If your usual cycle length is 28 days I would start CD8 just to be sure. Test every day and then multiple times a day so you can catch your surge.

Answer

Is it your first time testing? I started testing the day after my period so I could have a baseline since it was my first time actually tracking.

Answer

How long is your cycle?
