I've been getting bruises?

I've been getting bruises lately and I get insecure about it. They just appear and I have no memory how they got there. I have 7 on my left and and 6 on my right. My boyfriend has seen them and keeps asking about them. I don't get abused. The bruises do scare me, of the fear that I might something wrong with my body. I'm in band and I'm on my feet all day. I had bandcanp last week, all day and I don't know if being on my feet all day causes them? This isn't the first time, that these bruises have appeared, they'll go away and come back. It wasn't that long ago that I had the bruises. There more on my upper thighs and the bruises I get are like the size of a penny or a dime. I'm concern. Help xx
