No personal experience, but I teach NFP and one thing we teach those who are just coming off HBC is that their mucus observations the first month or two may be totally weird and not be in sync with their temps at all... therefore we teach a 5-day temperature only rule for the first couple of months, where you would look for 5 days of elevated temperatures to consider yourself in post ovulation infertility (this would be if you were TTA). If this is your first month off and you are TTC, you might want to wait one more cycle so the residual hormones are out of your system. Obviously they may still be in your system and are making things a little wonky, and the jury is still out on getting pg with hormones in your system...
