Hi girls! It's fine to start temping on CD3- you can start whenever you want! It's better to start before Ov, so that you can see your thermall shift (3 temps which are higher than the previous ones). If you start just before Ov it won't be as easy to see the difference in temps, but CD3 would be perfectly fine!
CHillbill- I think 10am might be a bit late in the day. I started doing mine at 9.00 and they were pretty erratic! You will soon get used to setting your alarm and waking to temp at an earlier time - I wake at 7.20 now, take my temp and then go back to sleep!
Good luck!
