hi, i am 4 months pregnant, and i have been experiencing heart palpitations, chest pain and pain my left arm. Mostly just pain in my left arm. I have been through the routine check for heart disease, which included a heart echo, and ekg s and have been seen by the top cardilogists in toronto, ontario. I can t seem to figure out what is wrong with me. Other doctors that i have been to said that there can possibly be a problem with anxiety, like an anxiety attack but I really and truly feel that this is not the problem. I am worried for my unborn child, which is not my first. I have never had any problems with my previous pregnancy, so I am wondering what is wrong with me. please help
