Newborn loud swallowing sounds

Hi mummies! My NB is 14 days old today but she has very loud gulping/swallowing sounds everytime she drinks. It would seems like she's swallowing very strongly. Then after the fed she'll breathe alittle faster like almost panting and will only calm down after like 10mins. she doesn't seem to be in distress, unhappy or uncomfortable.. Anyone experiencing this too? We've changed the bottle teats, fed her slowly, burp her during feed intervals but the sounds doesnt seems to decrease. Not sure if there should be any concerns here.
