It's a boy💙💙

We found out Monday our peanut is a boy! Docs asked us to come back at 28 weeks for another ultrasound. They say he either has a high arch in his mouth or cleft palate. I'm absolutely worried sick. He literally said, "if I had to make a bet, I'd say it's nothing at all" peanut measure a few days behind, but was completely perfect otherwise. Anyone else told this and had it be nothing?
