I am a 24 year old female. Having issues for the past week with shortness of breath, worse when laying down, feeling weak, extremely tired, confused, chest pains that come and go with excessive belching and discomfort. I have been to the er twice in the past week. All they did was moniter my heart rate, give fluids until it went down and sent me home. I had a diagnosed mitral regurgitation and bicuspid aortic valve about 10 years ago that never gave me trouble before. I have an appointment tomorrow at 11 am with the cardiologist... But should I be okay to wait til then ? I am kinda scared as it seems to be getting worse
