I will suggest you the best possible treatment options. 1 First do not panic. 2 I will suggest you to get a complete check-up of Hologram, urine routine, renal function tests. Get examined by expert in internal medicine to rule out cardiac or respiratory cause for your symptoms. 3 Your symptoms can be due to low hemoglobin or even some time due to physiological changes of pregnancy. But certain medical conditions need to be ruled out. I hope this answer helps you. Thanks Chat Doctor.
