At 5 weeks and 2 days of pregnancy, this is an important early stage where the focus is on supporting your baby's initial development. The most essential supplement to start or continue is folic acid, which helps in the proper formation of the baby's brain and spine and reduces the risk of certain birth defects. Doctors also commonly recommend a prenatal vitamin that includes iron (to prevent anaemia), calcium and vitamin D (for bone development), and sometimes iodine and vitamin B12, depending on your diet. In some cases, DHA (a type of omega-3 fatty acid) may also be advised for early brain and eye development. It is important not to take any medication on your own, including over-the-counter drugs, without checking with your doctor, as some medicines may not be safe in early pregnancy. Eating a balanced diet, staying hydrated, and attending your first prenatal visit will help ensure you are on the right track. Your doctor will guide you on the exact supplements and doses based on your individual needs.
