How long to wait to start another round?

How long is the wait to start another round? I was told three weeks or as long as you were on the drops, which one is it?

I am not sure either. I hear one thing for injections, another for hhcg drops. I did 3 weeks maintenance and now I am going to try P3/P4 for another couple weeks until loading Easter weekend for the next round. I hear round 2 is challenging. Started P4 with Ezekial bread...it is too tasty so I froze it until I can mentally handle it:)
