Hi Lauren. I get unexplained bruising all the time - more often then not it was when I was due for a period. After some blood tests my doc told me that it was something to do with my hormones, change in levels when mensturating and other "women" stuff and apparently "normal" for me (sorry, it was ages ago and I can't remember quite what he said). I still bruise quite easily, even from someone just lightly grabbing my arm (try explaining DH's finger prints on your arm at work!! ). I don't worry about it now, but I know that I did before. You may not even be aware that you are being bumped enough to bruise - I never am but often find a new bruise! I would get it checked out at your next visit anyway for your own peace of mind and to rule anything out. Maybe your just a delicate peach like me (at least that's what DH calls me!).
