Baby not feeding to one breast

Shawn

My son is 4 days old and i am all of a sudden having a problem breastfeeding on one side. Ok so when I️ try and feed him on my right breast all of a sudden, he latches and sucks a couple times and de-latches screaming. He will do this over and over like nothing is coming out. Once I️ move him to the left breast he is fine. Could something be wrong with the right breast? My milk just came in maybe late yesterday early today.
