What’s going on?

My baby turns 2 weeks on Wednesday- she’s been acting like she’s starving so I’m constantly feeding her, I can hear her swallowing and everything like I have before but just today she wants to eat eat eat - am I not producing enough? She used to be satisfied with a 25 mins feeding today’s it’s 35-40 mins & she still wants to eat- how will I know if this isn’t enough for her or should I be doing something else like pumping to make more?
