How long before af does cp change?

Does anyone know when the cp changes before af? Right now mines in extremely high an soft. Af is due around the 22nd.

I didnt want to read and run. From what I understand, your cp will change to firm and low around when you are to get af. But it can change from day to day too. CP is not really a good way of telling if your pregnant...but that has never stopped me from checking...lol
