Bleeding 😭

When I was pumping at work, I realized mid-session that I was bleeding. I freaked out because this has never happened to me before. Suggestions on what to do and how to help it heal?

Other info: the blood appeared to be from dead center of the nipple and I’ve never bled before. I bfed my 1st for a year and am almost at 7 months with my 2nd. Both were naturals and made breastfeeding a breeze.

I’ve been pumping since the start and have been pumping 3-4xs/ day since I went back to work 4 months ago. He’s never had formula, I don’t have a huge freezer stash and I’m terrified of stopping temporarily /losing my supply.

Any help is appreciated!
