Pumping question

herewegoagain • 👦3.2012~🧒9.2018~👶6.2020

So I have a Madela pump in style breast pump. I notice I dont relase more milk after about 5 minutes I typically have 2 let downs and dont get more than like 45 ml of milk. I was wondering if I should stop or continue pumping after these two initial let downs?

I was also wondering if anybody can teach me how to use it to get get maximum milk out. I've seen other post for different pumps that say ex: max 5 minutes then low 2 them max again 4 or something like that. Usually alot of people say it works for them so just wondering if anybody has that info for my pump. Not sure if I made sense lol thanks in advance.
