These tests are over the course of the past 2 days. I’m 3 days away from AF.

They’re in order.

Some were taken in the morning, some in the afternoon. I’ve heard urine concentration can vary the results...

Does it look like they’re getting progressively lighter? Has anyone had this happen?

If I’m going to MC, I just don’t want to be blindsided. 😢
