Hi mama, honestly folic acid is the main one your gynae would push for, so you're on track. Some mums take additional stuff like iron, calcium, or omega-3, but a lot depends on your diet and blood work results, so it's worth asking your gynae at your next visit if she thinks you need anything else based on your health. Every pregnancy is different, and what matters most is that you're following your doctor's advice rather than trying to match what everyone else is doing.
