I'm currently on cd20 in my second month of using CBFM. I have had a high everyday of testing this month since day9. Last month I got a peak on cd20. I've kept my sticks which are photographed as best I can.
Question: From the sticks does it look like I have ovulated and the machine has missed it? CD10 or 16 look possibilities to me. Any advice/feedback would be much appreciated, thanks.
