With 18.99 ng/ml on the 20th day of my cycle, does that mean I had ovulated by then? Am asking because I don't temp and looking at CM, I still get some, so I am not sure what it is supposed to mean? Also, do you get CM till the end of your next AF or does it stop at some point? what is it like? or when does it stop? Sorry a lot of questions in the end! Thanks Ladies.
