Leaky breast milk? Anyone else?

I just got sent home from the hospital today after my cesarean Wednesday, I've been pumping breast milk for my preemie in NICU, anyways, my nipples have been hurting, bleeding, yada. Which is normal, I bought some nipple cream, just rubbed some on, and instantly my breasts just started leaking, more like pouring down my stomach. Has anyone else experienced this? It's new to me. Lol
