1- with your temp do you do it the exact same time every day? On weekends do you set an alarm? I wake up every day between 5:15-6 and take my temp before I get out of bed and use a regular digital oral thermometer. It's kept bedside with my phone.
2- for OPK when do you start using them. I'm on day 4 of AF who will be packing up shortly. FF has my green day as NYE. (DH opinion is sex from the day AF leaves until the day I have a BFP, I think I won't be able to walk if we do that)
