I Have Unexplained Bruising On My Legs And Feet. I

I have unexplained bruising on my legs and feet. I had the marina coil fitted in December so could this be related. I itch my legs a lot since this has been fitting but not sure whether this could cause bruising.

I am 33 and reasonably healthy but I'm terrified I have leukaemia. Blood tests back on Thursday but that's a long wait for me.
