Getting worried my baby is gonna be BIG

Due date is in 3 days and no signs of labor. Now I'm starting to worry baby boy is gonna come out too big to wear any of his newborn clothes and diapers. Luckily we only bought one package of newborn diapers since we didn't know his size, but people bought us a lot of newborn clothes! I hope he can wear them for at least a few days lol!
