The hotline is best, however since you have already contacted the police that's an excellent step.
I don't know if they already recommended you do this, but if not, it would be good to have a 'rape kit' done at a hospital. They take genetic samples to prove sex occured and do stuff like photograph injuries and stuff. This helps to prove cases.
Of course sometimes there aren't visible injuries, this can make a case hard and it may be helpful to get a lawyer to help work with the state (they might provide one, I don't know how it works in various locations) to sort out your story properly.
