Am pregnant with number 3. Was an angel the first two times and took folic acid before starting TTC.
Am now 5 1/2 weeks pregnant with number 3. Walked past a chemist yesterday and remembered folic acid.
Have obviously started taking it.
I'm assuming there is no evidence/statistics on when the most critical time is to take it
(I know you take it when you are TTC and for first 12 weeks of pregnancy.)
