I don't know what you're in therapy for, but 3 months is really not a long time. She might feel that it's going well because she knows it's only the beginning, so things are normal for her. I've been in therapy for 2.5 years now, and for a very long time, I couldn't see any progress, I felt like it wasn't helping me at all. I guess that's normal, just give it time and try to talk about it with her if you need to
