I’ve been using  noogleberry for about a month now and I try to be very careful about overpumping, but it seems like no matter what I do I get those little red blood blisters around the cups (even with padding and low pressure).
I normally don’t go above -2.5 inHG , but sometimes I try for -5 because I’ve heard that’s the ideal pressure while still being fairly low. Any ideas, or pressures that have worked for you?

Thanks
