Prenatal vitamins

My doctor did a pregnancy test on me and it was negative, but she prescribed prenatal vitamins. My friend said that she probably prescribed them because I show signs of pregnancy. Is she right?

Dear L,

You should start prenatal vitamins before you are pregnant, when you are just trying, because prenatal vitamins are most important in the earliest weeks of pregnancy. The doctor should recommend prenatal vitamins to anyone who is thinking about getting pregnant.

Sincerely,
Amy
