2 months exclusive breastfeeding, no pumping

to all my breastfeeding mamas who only breastfeed and don’t pump.... my two month old has been sleeping more through the night and wakes up about twice.... I have noticed a decrease in my supply, my boobs aren’t as “full” and feeling more “soft” throughout the day....

however shes constantly feeding throughout the day and cluster feeds before bed..

MY QUESTION IS: do I have to pump throughout the night? Or is there such thing as “my milk could dry up” because she’s not waking up throughout the night?
