Dropping a pump

I’m almost 4mos ppd. Undersupplier at 19oz per day. Currently I pump 8 times a day. My schedule loosely is this: 4am (power pump) 8am, 11am, 2pm, 5pm, 7pm, 9 pm, 11pm. I say loosely because I’m almost always off 30 minutes to an hour. As I write this now, I’m an hour off from my 2pm pump because my baby has been napping on me for the past two hours. I love contact naps and the thought of me waking him up just to pump makes me want to cry. I never intended to exclusively pump it’s just what happened if I wanted him to get breastmilk but I also feel like I’ve missed out on so much of his newborn stage and I’m bitter about it.

I have been thinking of dropping a pump for weeks now. Can anyone tell me what to expect? According to the magic number chart, dropping to 7 would likely mean my supply will decrease so I’m so worried about doing that. Does it mean it will decrease to nothing? Or just lower my supply slightly. im fine with needing to increase his formula but I dont want to completely destroy my supply before 6mos which has been my goal. I just don’t think I can handle 8pumps anymore. I want a life. I want to spend more time with my son and take care myself and my mental health.
