Its ok if there's a little blood in the milk. It won't hurt him any if your healthy (ie: not positive for any stds/HIV/AIDS). If you really think about it, breastmilk is considered a blood product in the medical community, so a few red blood cells won't hurt him any.
I do reccomend you find a la leche league leader. There is usually a leader willing to give help even when the LC places are closed.
Best wishes!
