CBFM - does anyone use second morning urine?

[artylady14]

I have tried using CBFM and not got any peaks, even when I definitely ovulated. I read online that someone was using her second morning urine and then got her peaks. Does anyone else do this?

Did it again today and still getting highs..Anyone else tried this?

Yep, when i used to do them many moons ago, I sometimes used pee about 11am (so roughly my second pee). i sometimes did them in the afternoon though if I had spare sticks to see when the ovulation peak had gone.

Thanks. I had a temperature dip today and what I think is a positive opk but I am still just getting highs on the cb fm. It just doesn't seem to work for me
