Help. Advice. Doctor?

So i cut myself with a razor. It had got a bump on my vagina. It was a huge a bump under the skin. A week later it popped now its like a huge opening. Not that huge but big enough to see it in a mirror. The problem is it won't stop bleeding. This is day four its still bleeding. I put peroxide on it but it didn't work. The bump is red. Its going down but im just frightened. What can i do to heal it i swear im never using razors again. It wasn't even the cheap one. I paid 24$ for my Venus razor and this happens. Is there anything i can do to heal this?
