Symptoms: dizziness, weakness, shortness of breath, blurry vision, seeing flashes and pinpoints of light, chest pain and pressure, slurred speech, loss of appetite, nauseous, difficulty sleeping, trouble thinking right. I am seven months pregnant. These are the symptoms I live with everyday. I have gone to the ER several times, have EKG and many tests done and everything always comes back normal. My doctor says that it is all due to my anxiety or either it s pregnancy-related. But I am extremely afraid that all these symptoms has to do with something more than just anxiety. Two months ago, I have been diagnosed with tachycardia. I have never had a fast heartbeat until this pregnancy. Is there anything I should be worried about?
