Day 2 breastfeeding and bleeding

Amariev92
Today is my second day breastfeeding and we have had trouble latching onto my left breast. The last time I thought we had a great latch but when she was done eating I say that she tore my nipple and it's bleeding. It is very tender and painful to touch I don't want her to feed from it anymore because it hurts so much but I know she has to. Any advise?
