So I thought I had a pretty good grasp on all things TTC, but now that we're getting into it, I feel like I need things explained to me more clearly.
Can someone explain how OPK's work and how to use them?
I'm getting ready to order that Wondfo combo set of Ovulation tests and pregnancy tests from Amazon.

So, a very clear explanation using as few acronyms as possible and assuming I know very little about anything. lol
