My son is always grunting and I’m starting to get worried

Li

Since yesterday, almost m any time my newborn has been awake he has been grunting and seems very uncomfortable and I’m so concerned. He doesn’t cry he just makes these noises like he’s struggling to poop or pass gas, but he does it constantly. He is having plenty of poopy diapers so I don’t understand. I gave him gripe water yesterday and maybe it helped a little? Should I be worried ?!
