You can start during AF just to get yourself in the habit of temping. However, temps during AF are generally pretty erratic, so a lot of people normally skip it. Also, it took me a few cycles to get the hang of temping, so don't be discouraged if you don't get clear info right away. I only started after TTC; I'd think that 1 or 2 months of practice would be sufficient, unless you want to feel like you're doing something besides waiting during the 6 months until you start TTC.
