Skipped 2 MOTN sessions and output decreased

I am 9 dpp and am so so tired and sleep deprived. Last night for the first time in forever I finally let myself sleep and skipped 2 pumping sessions at midnight and at 6am. Today my output decreased by close to 30-40% and my boobs are not as stiff. This was surprising to me, I know it’s all about supply and demand, but I didn’t realize it’s THAT sensitive. For reference, I averaged at 7ppd and diet, stress level etc was the same so far. If anything I thought today’s output would be ok because I’m a lot more rested and less stressed.. does this mean I’m basically screwed and absolutely have to maintain the same amount of MOTN pumping? 😞
