Helpful yes. Prudent, not so sure. I was once chase by a "homeless" man that I stopped to ask if he needed help (it was a very hot day and he looked a bit out of it). If I was the OP I would have called 911 as soon as possible and reported the woman.
OP, I am glad that you are OK. I hope the woman is OK as well.
