Hello guys im new to this bbt charting thing, and I am currently on bc(the pill) but this is my last month on it. AF is due Dec. 24th. I am planning to start taking prenatals from January 1st. And then I would also like to start recording bbt as soon as my period stops. My husband and I are planning to start ttc starting april 1st. If I tract for the 3 months until april is this enough time to get a good idea of when I will ovulate? Or is this to short of a time period to notice a pattern?
