Breast Milk Supply Drying?

My daughter was born 5 weeks early and as a preemie she was placed in NICU until she could go home 17 days later. Being at the hospital made it easier to pump because I pumped in between her feedings and was getting a decent amount. (Her jaw strength wasn't well so she wouldn't latch onto the breast in the beginning). She latches now but only for a few seconds. Still trying though. She got used to the bottle but since she still roots around when she's at the chest I'm still trying to get her to latch.

Anyways being home and with the holidays and family it's been hard to pump so often. I noticed the supply adjusted itself but now twice I've only received a few drops from each breast which amounts to less than 1ml. She is 6 weeks + 1 day and is pretty much being formula fed.

Is all hope lost? Is there a way to increase it with me only getting a few drops now? It literally looks like mist in the pump when I do.
