I've also heard that taking folate only makes a difference pre-pregnancy and the first trimester. That makes sense because the 12-week scan tells you if there is a likelihood your baby has a neural tube defect.

I didn't take anything afterwards BUT my obstetrician had taken blood tests which looked at all my vitamin levels etc.

If you're at all concerned about whether your diet will be giving you what you need, just get a blood test done. That will give you the answers you need.

All the best
