I cut my nipple 😬

Wendy
I was shaving my legs this morning and somehow when I turned to rinse the razor I managed to cut my nipple with it....
I don't know what to do, I've expressed some breastmilk and I'm letting it air out. It's not bleeding anymore, in fact it stopped bleeding quite quickly. 
Should I pump on that side for a bit? Use polysporin? 
I guess sleep deprivation and sharp objects don't mix... I just wanted to feel human again ugh
