Cluster Feeding

My daughter is three weeks old and every night starting around 9:30-10pm she starts getting restless/fussy and feeding every 30 minutes to an hour, sometimes lasting anywhere from 10-30 minutes. I have to switch off breasts when this happens. Is this considered cluster feeding? How long can I expect this kind of feeding routine to last? I should also mention that 9:30-10pm is my husband and I’s bedtime, which makes this cluster feeding especially inconvenient! Any tips on how to survive this?
