I just found out im pregnant and reading everywhere about folic acid being important for the baby's brain and spine. I started my tablets a bit late so now im worried i missed the window. when exactly does this part form?
Very early, like by the end of the first month. That's the whole reason folic acid is started before conception itself. If you are planning, start the folic acid now, dont wait.
It happens in the first month, super early. The key takeaway is folic acid early. If you have any specific concern about timing or supplements, your gynac is the best person to guide the dose.
The neural tube forms and closes really early, around 3 to 4 weeks after conception, so basically in the first month. My doc said that's exactly why folic acid is recommended even before and right at the start of pregnancy.
I read about this while planning, it develops in the first few weeks, around week 5-6 of pregnancy counting from last period. My gynac put me on folic acid before trying for this reason.
