I hope you called your dr right away! Women often do not have chest pain the way the text book says. We can also have heart attacks while still having periods, if your Dr. says this does't happen get a new Dr. Any time you have pain/ pressure in the left arm/chest/ jaw or for us in the chest, especially if you also have nausea/tiredness/weakness/sweating...call your Dr. right away. If it persists... call 911
