TTC to plan childs birth month?

Has anyone "planned" on getting pregnant at a time where you would deliver in a certain month? Like,think about which month you would like to give birth and then ttc accordingly? Ex: I have 3kids. Bdays in Oct and twins in August. So I'd like to have a baby around Feb-April. If we ttc this month baby would be born around then. I obviously wouldn't care when their birth month is,but, I have thought about this. (Ive always got preg 1st try/1st cycle.almost too fertile!)
