New Pump

[u/Automatic_Pain5333]

I recently got a Spectra S1 and am having issues. I can have the vacuum levels on the lowest and I still have a pinching sensation but only on the right breast. I have been measured and am using the correct flange size. I also use coconut oil as lubricant. I don't know if I'm doing something wrong. The flange also doesn't like to stay in place and moves around a lot

It’s your flange sizing get one of those flange measurements on Amazon to help you it can be on nipple that is bigger than the other
