hey ladies,

I'm sure I can find the answer around here somewhere but I'm honestly so confused. I started testing at the beginning of my cycle just to see progression and I'm currently on CD17. I have a constant, normal af(about 29-31 days) this morning I got a dark test strip but my clear blue was negative. did I maybe miss the surge last night? I usually test in the afternoon with the strips and use clear blue every other day. I wanted to track this cycle because it's my first time doing so and I'm honestly more confused now haha.
