Bleeding nipple?

Chelsea
So im 5 months into breastfeeding and I have had no problems since the 1st week, but I wokeup this morning to little blood spots on my right nipple (she mainly only eats on that side) it doesnt exactly hurt, but when she was eating it felt like I had an extremly fast letdown and its not hurting while she's off of it. Is this normal? I'd feel kinda silly going to my doctor for this lol
