At 16 weeks of pregnancy, if you have no complications, the need to continue Endogest 200 SR depends on why it was started (such as previous miscarriage, bleeding, or cervical issues), and it is usually continued only for a specific duration as advised by your doctor, so you should not stop or continue it on your own without confirming with them. During this stage, the most beneficial supplements for you and your baby typically include folic acid, iron, calcium with vitamin D, and sometimes additional nutrients based on your health needs, along with a balanced diet, good hydration, and regular antenatal check-ups. If you are feeling well, that is reassuring, but it is still important to follow your doctor's plan and attend routine scans and tests to ensure a healthy pregnancy.
