Answer:
As soon as she starts trying getting pregnant (stops taking birth control)
Explanation:
Folic acid during pregnancy is important during pregnancy because it decreases the risk of neural tube defects in growing babies.
Birth defects usually occur within the first 3 or 4 weeks of pregnancy, that's why it is important to have folic acid in your system during those early stages since this is the time when the baby's brain and spinal cord are developing.
That is why, ideally, you should take folic acid supplements for two to three months before you conceive and until you are 12 weeks pregnant.
If you are actually planning to get pregnant, your doctor will tell you to start taking prenatal vitamins with folic acid.
Sandy and Bud are thinking about becoming pregnant in the next few months and she stopped taking birth control. Since they are planning to get pregnant, she should start taking prenatal vitamins with folic acid already.
