Hi. welcome to healthcare magic. Congrats on getting pregnant. Folic acid
supplements of 5mg daily are recommended right from day 1 of conception till the end of first trimester for proper brain and neural tube development of the child. Now- a days it is combined with Vit B12 supplements also to avoid other congenital defects and threatened abortion
. Hope this will help you. Happy childbearing.
Dr. Rakhi Tayal
