You normally get however many highs (everyone is different) followed by 2 peaks (you usually O on the second peak) then one final high (just to make sure) then lows until AF. The highs are when the CBFM picks up LH which can be all month long and it peaks when it picks up oestrogen. If you're getting highs after O it's just LH it's picking up.
Are you positive you have got this the right way round ickle. I thought you got highs when CBFM recognised that your oestrogen was rising, and it peaked when it detected the LH surge. Don't you have oestrogen in various amounts all through the cycle, whereas LH is released to tell the follicle to burst and release the egg?
Whichever way round it is, I do agree that you are wasting sticks testing now filipenko and that you will confuse the monitor if you don't reboot it, rather than just reset it. I can understand the need to POAS but to be honest you would be better using straight OPKs and HPTs rather than the monitor at this stage as there is no chance at all that the monitor can give you any reliable information, whereas the others just might tell you something worth knowing.
I've had a really productive day clearing clutter and tidying up in our combined study/children's playroom. Still have about another day's work to do mind you and not sure when I will find that free day, and they will probably have trashed it again before I do, but I have 3 large black sacks of rubbish to go out, 1 box of stuff for freecycle and 2 boxes of outgrown baby toys for the loft to come out WHEN not if this next baby comes along
