Breastfeeding 4 week old

My baby is about to be 4 weeks old and recently fussed so much when feeding like she’s so frustrated . It sounds like she is gulping and I’m guessing a fast flow is bothering her. It’s not all the time but it is often. More so on my right boob than my left but it still happens on the left too. I honestly don’t remember if this happened with my last 2 kids and it just got better with time. Does anyone have insight? It’s just frustrating especially for a night feeding.
