Happen To Be Experiencing Slight Chest Pain---nothing Major. But I

Happen to be experiencing slight chest pain---nothing major. But I happened to look at my heart rate reading on my Fitbit. It was 65 but now up to 70.--then back to 68. I take 50mg of atenolol daily for high blood pressure and 10mg of prozac. I exercise 2-3 times per week and otherwise feel fine. Should I be concerned?
