Cluster Feeding only at Night?

My one and a half month old usually eats every hour to two hours but at night usually starting around 8:30 she wants to eat every 30 minutes, or pretty much just wants to stay on my breast until about 12:30-1:00 am... I feel like she sucks me dry and just wants to keep sucking, my nipples hurt so bad because she's always on and I'm not sure if it's cluster feeding or I'm not making enough at night?? Anyone have any advice? I don't know what to do.
