How long do you have a LH surge?

I tested on Tuesday and it showed it was high and tested out of intrest today and its still very high, so thats like 5 days. CM was stringy day before and yesterday too.

You can have more than one LH surge throughout the month; this is why opk's are beset with problems. These assume that women only have one such rise every month and that such a rise is immediately followed by ovulation. Both of these assumptions are not true.

eek so its best to go with how my cm is? Thanks for that info attila though. Much appreciated

Interesting, I had an unusually peak on my fertillity monitor but no EWCM. Was a week early but last period a week late. Do you think even a fertility monitor can detect a surge unrelated to ovulation?
