Bleeding nipples!!

Today my daughter turns one week old, I've been breastfeeding her since the moment she was born. I'm nervous that I'm doing it so wrong :/ my nipples are bleeding and she will only latch on one breast the other one I have to use a pump or it gets hard. I need help..

What can I do to ease the pain because I am in so much pain?

How do I get her to latch on the other one so I don't have to use the pump? Any tricks?

How do I get my nipples to stop bleeding?

Thank you 😞
