If tt's what ur gynae prescribed it's fine. For me my gynae gave me fish oil and prenatal vit as I didn't have enough in my diet (I hardly eat vege and fish). Tt was when I was 8 wks. Really depends on indiv, if u have balanced diet, folic acid alone is enough. Some moms don't even take folic acid but tt's not usually encouraged as u may not get enough of it frm food unless u're super strict on ur diet.
