FOLIC ACID

Is is okay to take Folic Acid kahit medyo nalate na? First check up with OB was 16weeks preggy nako and folic acid muna nireseta nya with medyo high mg na para mahabol daw yung buwan na wala akong folic acid. Im now in 19weeks. The next check up, dun na daw nya ako bibigyan ng mga vitamins. Thanks in advance mga mamsh ?
