Charlie saw Bella just about a month after the wedding. At that time Renesmee looked to be about the size of a three-month-old. Obviously, some serious fast-forwarding occurred if the baby was Bella's own. I don't think Charlie had any reason to suspect that Bella lied to him about being pregnant before the wedding.
