Macbook Air 2018

Hi, my macbook air ran out of charge over night. I have put it on charge (currently for 4 hours) but it won’t turn on. It keeps restarting with the restarting swooshing noise and sometimes an apple symbol in the middle but seems to be stuck in a cycle of restarting and turning off. I’ve only had it a couple of days and don’t know what to do??! :(
