Anxiety, medication and pregnancy

I suffer from severe anxiety and panic attacks sometimes the only way I can get through a day is with anxiety medication. I have been in therapy for a few years, and while my symptoms have eased, and I no longer have regular attacks, I worry what might happen while pregnant. With that background, does anyone know of any medication, herbal or otherwise that is safe to take while pregnant to alleviate anxiety. I would like an arsenal of suggestions before seeing the doctor. Any advice would be greatly appreciated.
