Cbfm question!

[studentvera]

I've had a peak cd 13/14 for last 5 cycles. This cycle I'm on cd 18 and still high.
Can the cbfm miss a surge or can you not ovulate some months?
Have dtd the last 6 days - but feel there is no point with no peak :)

Anyone had this?
Thanks in advance!

Either - sometimes it can not detect a surge even if you have one, and sometimes you'll have a month where you don't ovulate (it's normal to have 1-2 a year).

Or you could be pregnant ... My cbfm was high from cd8 the month we conceived until I found out I was pregnant. Never got a peak.

We didn't do it on the peak as we're shagged out by that day...still fell pregnancy just in the highs.
