Theres still time!! lol
Apparently it takes the monitor a little while to get to know your cycle, you might get a peak in a day or two. THat being said you may still ov and not get a peak on the monitor as its ur first month! Hope this helps put ur mind at ease a little, there are other girls on the forum that are experts on the cbfm!
Im on month 3, got 2 peaks and 1 high on cycle one, then last cycle i got highs from day 8 right the way through to day 20!! and no peak! So far this month iv been getting highs since cd6, now on cd9 so expecting a peak tomorrow or monday! Fx! xx
