I damaged my vagina, and I'm not sure what happened?

So, yesterday, I was at one of my dance performances. I squatted down a bit to help out with props without realizing that there was something behind me and part of it was under. When I squatted, there was pressure on my vagina. It hurt bad. It was probably somewhere around my clitoris or a bit below. Not too sure where. I had the goosebumps for a while and after about 5 minutes, I went to the bathroom to find that I had bled a bit. The blood stain was up around the area of my clitoris or below [that's how I guessed where I had been hit]. I went to go get a pad, but at the end of the day, there were no stains on the pad. I'm not too sure what had happened. I actually think I didn't hit my clitoris directly. Probably somewhere lower. I don't know too much about the parts of the vagina either.. help anyone ?
