Normal for milk to leak all the time?

I’m exclusively pumping because my daughter is in the NICU. But my boobs drips milk all the time.

Like even just taking off my shirt and getting in the shower real quick, it drips down my stomach or onto the floor.

Even after I pump they’re still leaking. I’m pumping every 3 hours or so for 20 mins each. Should I pump longer? Or is this normal?
