I think I've lost my supply

FTM - needs help ! I was BF my one month old so well the first 2-3 weeks. At 3 weeks he developed thrush and I had backed off from BF and was supplementing and pumping. We the overwhelming care for him and myself I slacked off on pumping and I feel like my supply is gone. I don't know if there is anyway to get it back? Im starting fenugreek caps and I'm just wondering is there anything I can do or it's done? This pic below is what I pumped on one side for 30mins today. The left side produced nothing.
