This is a VERY STUPID question. I'm going to call my doctor and get some advice but need some clarification first so I don't feel like a complete idiot when I talk to her.

Is the idea that you get one positive OPK per cycle? I had assumed that once the LH was up it would stay up and that I'd see positive OPKs throughout the second half of my cycle. I had a positive OPK yesterday and then a negative today. Is this fine?

The reason it's weird is that I'm testing two different OPKs. The one (digital) gave me a positive yesterday, but the other (non-digital) has given consistent negatives.
