So my Cf went from being creamy to watery..Today makes 12Dpo and Cycle Day 23! Waiting to test Wednesday and supposedly Af on the 17th! I went back to my notes from the previous months and this is the first time after O that this has happened it's usually just creamy days until Af....

Have you experience this????
