Hi, I've been using cbfm for 6 months or so now so it knows me quite well- I was surprised to find out ov is usually a bit later than I thought- I tend to get 2 days of high and then peak on day 15. This month the first day it asked for a stick was day 6- and it gave me High straight away. This doesn't seem normal patterns for me- has anyone had this too? Wondering if I'll now have 10 days of high?
