Not able to take folic acid

Hello po! Sobrang natatakot na po kasi ako about sa development ng aking baby. I wasn't able to take folic acid during my first 12 weeks of pregnancy. Ask ko lang naman if may hindi nakapag-take ng folic acid or late na nag take at nagkaroon po ng defect sa baby nong nailabas na? I appreciate your responses po. Please 'wag nyo sana ako pagalitan, since I'm a FTM. I am very curious lang po talaga and scared at the same time. Thank you pooo #18weeks #FTM
