Baby’s testicle hasn’t dropped

Since our first checkup our pediatrician has said the baby’s right testicle hadn’t dropped yet and our last visit two months ago he said if it still

Hasn’t dropped on his 4 month checkup he would refer us to a specialist (I think that’s what he said) anyway I’m super worried. It looks the same like it hasn’t filled out. I’m just so nervous about this, his checkup is on the 15th.

Thank you everyone.
