S.H.
She's just a newborn so their digestive system is not yet fully developed and even getting gas out can be hard.
At the hospital, the nurses would hold the baby, (their front side against your front side or to your chest), and rub/massage their backs going upward.
Or, gently massaging their tummy in circular motions as you held them or as baby is lying down.
And, keep your baby upright after feedings for about 1/2 hour if possible... so they don't choke on their spit up and possibly aspirate.
My daughter, had gas problems... and rarely farted or burped. And it would cause her gas pains and crying. We gave her infant gas drops which helped a lot. The gas would get trapped in her and cause pain.
If anything, ask your Pediatrician.
All the best,
Susan
