Puppy Jumps

Adreanna

So I have a 3 month old puppy. He weighs probably 35-40 lbs and has a tendency to jump DIRECTLY on my stomach. I'm 28 and a half weeks pregnant. I'm trying to get him to stop but he's so quick. He launches off the floor directly onto my stomach and right back off. Should I worry about my little man on the inside?? Anything I should watch for??
