What do I do about my nail being gone?

I was attempting to peel a small portion off and the entire thing just peeled off… It doesn’t hurt or anything and it only has a little blood. It’s not even to dripping point, but I don’t know what to do about it. I don’t want small pieces of sock in it and have to take them out every night. I have no bandages. What do I do and how long should it take to regrow?
