I found my pulse rate is higher (sometimes more than 100 / min) during my pregnancy. Does it indicate that I am still pregnant, means I need to know, Does it remain same high even if the fetus go dead inside ? And I don't know?? Please answer I am getting anxious every day. Also, what are the factors that may lead to develop a chance for any child being autistic or having problems with heart /valve or other organs even if anatomy scan is ok.
