However,
If there were traces of blood outside the body and it was dried then HIV doesn't live in dried areas outside the body. So, it is less likely. You could get tested but I think your risk is low.

You can't always see traces of blood. So if suspect she has HIV then you should get tested. If she hasn't had any other partners then obviously there is no risk but if she has had a lot of partners in the past it is a slight risk.
