CBFM wierdness

[WhosPickleisThatOnion]

I normally ovulate really late on last few months it was days 22 and 24. I've just started using the cbfm and it's gone from low fertility to high egg alert overnight, on cd13.

Has anyone else had this? Wondering if it's just getting used to my levels or something. Very odd!

This doesn't really answer your question but i'm in the same situation.
normally ov on cd18 but started using cbfm this month and got peak fertility readings on cd10 and 11 (was low fertility reading the day before). I know it shows a peak reading a couple of days before ovulation but this seems very early for me too.
Don't know if maybe the monitor takes a while to get used to the user or what. I agree it seems odd

It does take a few cycles for the CBFM to get used to what is normal for you. Some people have low levels of hormone, others high levels.

I have just bought some normal ones and they are positive too - must just be ovulating early this month for some reason!

Maybe you ovulated early as well emmalou as mine seems to be right.

I didn't even get a positive OPK until CD24 last month.

how do you know you were ovving before CBFM?

i had this and reckon i had ov timings wrong before CBFM....

Good luck!!

I was using Ovulation kits so I'm pretty sure I was right. I hope it lasts as my last cycle was 37 days and this is much better!
