Broken pump

Kiara • ~🥰Momma to 2🥰~
My pump isn't working well and its seriously stressing me out! I have the Ameeda purely yours double electric pump, and I have no idea why but little to no milk is coming out. I've checked all the parts and none are damaged. I don't have the money for a new pump right now, and have resorted to hand expressing but it takes forever and my arm is usually very sore after.  Plus my job doesn't like that I've been taking longer on my pump breaks. What should I do? I'm stressing out 😩
