Also, sometimes temps can start to rise before O, as I've unfortunately discovered through monitoring at my RE which can give you the wrong O date. I don't know why my temps did that this cycle but they did. My RE was giving me u/s and taking blood every single morning to pinpoint ovulation for the last two cycles and the cycle before this, FF would have given me the wrong date (and this cycle my temp started to rise before O). So take charting with a grain of salt, it could be off by a couple of days..
