Do Finger Nails Grow in Thickness?

Well first off i banged my finger between some plates at the gym around 2 monthes ago. So it was like completetly purple underneith it for a long time. Now finally some of it started to grow to the end of the nail.

But this is what i find weird. If i scrape the outside of my nail i can scrape some of the blood off. is it possible that finger nails grow in thinkness and the blood somehow rose to the top so im able to scrape it off?
