Large booobies and trouble emptying

I am 11 weeks post partum, since week 2 I have exclusively pumped. I average between 37-40oz. It’s always between this, i pump 5 times a day, sometimes 4.

My 3am and 10pm pump are the lowest at 6oz
Morning session is around 11-14 oz
And 8 oz sessions between.

My issue is that I pump for 25-30 mins each time, and when I squeeze my nipple, it either still sprays or still consistently dripping. Does this mean that I am not emptied? I really don’t have it in me to sit there for much longer

I use the s12 Momcozy pro. Would getting something like the spectra help this issue? Another issue I have with the wearables is that they are chunky and I can’t find a supportive bra and I feel like I can’t do anything besides pump as I feel like even if
I lift my baby they will fall out from the top.

Are wall pumps more secure?
