What happens if I didn't start folic acid during my 7 weeks of pregnancy?

Not starting folic acid early in pregnancy can raise some concerns, primarily because folic acid is crucial for the prevention of neural tube defects (NTDs) such as spina bifida. These defects affect the development of the fetal spine and brain and are most likely to occur in the first trimester, often before many women know they’re pregnant. That said, starting folic acid now can still be beneficial. The neural tube formation occurs roughly in the first 4-6 weeks, so while the critical window might have passed, some evidence suggests there’s still benefit to taking folic acid through the rest of the first trimester and even beyond. It’s a recommended part of prenatal care due to its role in the overall growth and development of the fetus. You should begin taking a prenatal vitamin that contains 400 to 800 micrograms (mcg) of folic acid immediately and continue throughout your pregnancy and even in the postpartum period if you plan on breastfeeding. These supplements are usually readily available at pharmacies and grocery stores. Beyond folic acid, ensure you’re adopting a healthy lifestyle— a balanced diet, regular physical activity as advised by your doctor, and avoiding alcohol and tobacco products can all contribute positively to your pregnancy. If you have any lingering concerns, especially regarding any potential risks or your personal medical history, it’s worth discussing this directly with your healthcare provider.
