What is this bump on my leg?

[far2019]

I have had this bump for probably about 6 months now. It has definitely grown since then and started as a tiny thing that I though was just a scratch. It changes color ranging from red to a dark purple. It is a defined shape and has kind of a central point in the middle that is darker than the rest of it. It also will lighten up and turn pretty  close to my normal skin color when I press on it. It doesn’t bother me in the slightest, doesn’t hurt or itch. However though, whenever I accidentally shave over it, it bleeds.... a lot. When it starts off, it pretty much profusely bleeds for like 10-15 minutes and will continue bleeding until the next day (yes, a full day), but it’s not a lot after the initial bleeding, just a little spotting. The first time this happened I freaked out obviously and now i’m very careful when shaving. It hasn’t been that much of a priority for me because it isn’t painful or bothersome but I still am curious as to what it is. It looks slightly similar to a dermatofibroma but it doesn't dimple in when I squeeze it, which is a characteristic of a dermatofibroma. Any suggestions? Thank you!
