This should be checked out. As you said it is not normal. One thing you might do is start collecting data. Keep a log of your heart rates (and blood pressure if you have a monitor available) regularly at times throughout the day. At rest, before and after exercise, etc. Take not on your log of the times you have chest pain or shortness of breath. Have you talked to your parents about this? Maybe they can support you when you go to the doctor. You might need to see another doctor to be taken seriously, but sometimes representing with the same symptoms persisting and more data convinces a doctor to take you seriously. If your chest pain or shortness of breath worsens you should call EMS and go to an ER.
If you take oral contraceptives (birth control pills) I would be very concerned about your symptoms, especially if you also smoke. OC increase your chances of having blood clots and pulmonary embolus, more so if you smoke. PE is life threatening and must be treated at a hospital.
