When cluster feeding isn’t normal?!

My daughter has gradually upped her game of cluster feeding. Starting from 6-12pm, it went to 4pm-2am... last two days it’s also been from 7:30am... all day. Quite often with 15min breaks and if im lucky a whole hour 💤😴. She is just over 4 weeks and when she isn’t cluster feeding she feeds every 2-3hrs.

Is this normal? Online I only read others experiences being a few hours in the evenings!! Im close to caving in and topping up with formula, I can’t keep up with her and everything else going on 😢
