Baby sleeping through the night

So my baby is a little over 2 months and she is sleeping about 6 hours at night now. I am EBF now since her nicu stay and she is doing great! My question is as she stretches out her sleeping at night how will my breasts/supply react? I woke up for the first time this morning so engorged but she has been sleeping for 6 hours for about 2 weeks now. I pumped after she ate and I feel better. I just didn't know what to expect or if I needed to modify anything as she started stretching out her length of sleep at night even more. Thanks!!! :)
