Has anyone entered their TWW without knowing exactly when they would ovulate?

So, this is our first round trying. Donor is only available on Monday and Tuesday; I'm expecting +OPK on Friday (so it's right at the edge of the window). I'm usually pretty regular, with the occasional WAY OFF.

We did our first insem last night; I know chances are great if my +OPK comes early, chances are OK if my + comes on time, and the chances are slim to none if my + comes late. I'm obviously going to still test until I get a positive, but I'm gonna be super bummed if we missed the window and this was just a test run 😬
