I think it's according to how much you need to contact her, with the situation you're in I don't think she'd be surprised if you contacted her every day. Even if you kept a day to day journal through email to her of what happened that day. or maybe every few days. If she thought there'd be a chance of too much contact she'd have told you how many times, but she said, she trust your judgment, so to me it sounds like if you need her to contact her.

I am so sorry you're in this situation, I can't imagine how stressful and anxious this is making you. I wish you had another alternative.
