This is my first BBT I know I am missing some temps, my doctor said dont temp because I'm on letrozole CD 5-10. I've read though if you're going to temp to temp 2 days after the last pill which is why I started temping late. Anyway when I put today's temps into FF I got 2 red lines and my coverline went away. I also recieved a +OPK CD 13 if anyone needs to know. I'd appreciate any advice in ANY way possible as to what the 2 red lines mean AND how to read this chart as again I am new to this BBT. I just would like to find out if I'm actually ovulating or not or what is going on.
