My girlfriend has been bleeding down below... is it contagious?

If your girlfriend is bleeding and it is not her monthly. You need to get her into the hospital immediately and not wait with this. It could be a number of things. From a failed pregnancy to something serious.

And no it is not contagious but it could be a disorder and it could be something else.

A physician can give you better advice.

I would not wait or give this time to get worse as it could.
