Night pumping?

I have worked very hard to create enough supply for my baby. Just got the clear from my doctor to stop supplementing with formula! So proud of my hard work and dedication over hear last 8 weeks when everyone told me to give up. Anyway, now that I'm making milk and she's sleeping six hours I wake up with huge sore boobs. I have read this can hurt supply and wanted to see if anyone pumped in the middle of the night and if they still had enough milk to feed when baby wakes.
