Women's cycles can change due to diet and stress. Also, I would suggest calling your gynecologist and your therapist. Birth control pills can help regulate your cycle, however you would be introducing a hormone into your body, so I would let the therapist know. Beside these doctors have had many patients, they have heard it all. You are not their 1st patient that is experiencing something "new". But in order for any doctor to be able to help you or treat you they do need to know the "whole" picture. Please be honest with them or they cannot treat you properly. Good luck!!
