Help on conceiving

Mary • Hi my name is Mary. My husband and I are trying for baby #3! ? But I want to plan when not just have it happen!
I am trying for child #3 and I want it to be on my terms not just something that happened. Is it best to not have sex between ovulation at all cuz I heard that not having sex makes the strong either more or stronger. And when is the best time to have sex? Every day of ovulation or when?
