I am 5' 9" and have 50cm and 52cm road bikes and a 15" mtb my inside leg is just over 32". The rule for men doesn't quite work for us girlies as our leg/torso ratio is different (hence the reason they make women specific bikes).
Go for Medium - approx 50-52, sloping top tube so not exact, the small is 44cm and the larde is huge. to get a correct fit change the stem for longer/shorter or get an adjustable stem (what i did)
JJ - they reckon that you can finetune your position with the length of the seatpost and an adjustable stem. I think it works for most people, unless you have unusual body shape. For example Moosey's basalisk like neck. (!)
As ML says - you can get girly specific bikes, but not many of them around really.
Although maybe before we leap onto this, we should just get you riding anything. I'll have to do an e-mail lesson on riding a bike ! (really dunno what goes on there, but I expect I'd fall off if I had to think about it)
frame sizes are different for sloping downtube bikes but even a ordinary bike shop like halfords should be proficient in measureing you right. as has already been said seat post crank length and handlebar stem can all be changed to adjust your position to get you comfortable. although this can take some time so be patient with it.

Now then... There's a boney bit in your chin?
I think mine is a medium ?
