Hi,

I'm using the clearblue fertility monitor and have been for quite some time.
It's always been pretty regular an lh surge around day 11 and peak on day 13-15.
This month lh surge started on day 10, I'm now on day 17 - lh surge still high and no peak.
Cycles vary between 28-30 days.
Slightly confused as to what's going on. Any ideas would be appreciated.

Thanks so much

Michelle
