Unknown bruising

Let me start off by saying I know I should see a doctor, I’m currently working on getting my insurance figured out.

Anyways, for the past three or four months I have noticed random bruising, that I have no idea what from (at work I don’t really bump into things, and I’m normally just with my boyfriend otherwise, he doesn’t touch me hard enough to leave bruises). They started off as a few very faint bruises and they have been appearing in odd places and becoming more dark. The only reason it’s actually concerning me is because since the bruising started I have lost between 30-40 pounds, and an extreme loss of appetite (normally eat one small meal a day).

I’m curious about if anyone has been having/has had these happen and what they found out the cause was.
