If you get extremely cold and look pale or for no apparent reason, you may begin to tremble.

What is the reason of this?

Hormone changes during pregnancy can sometimes cause women to feel hotter or colder than usual. However, your immune system does not work very well during pregnancy, which can make you more susceptible to infection or illness. Chills accompanied by fever, nausea, or vomiting may be associated with a cold, flu, stomach upset, thyroid problem, or urinary tract infection. Less commonly, chills with high fever and pain may be associated with a bacterial or kidney infection.

Tips

It's not a bad idea to talk to your doctor if you experience tremors during pregnancy, especially if it's accompanied by other physical symptoms. It could be a simple case of hormone fluctuations, or it could be the result of a treatable illness unrelated to pregnancy.
