Hi, I'm Dar, this happened to me on my 4th pregnancy. It seems that my throat beat 3 times fast, and I felt nervous coz I didn't feel it before, but will last for a second.now I'm on my 7 months and it still there, my hart palpitations for a seconds,I'm afraid. I've been to a cardiologist. I had lot of laboratories, 2 d echo, lipid profile, thyroid panel, blood sugar test, and it's all normal.what is this strange I'm feeling during this pregnancy?
