Folic Acid dosage ?

Hello! i’m at 4wks now have yet to see a gynae/doc yet cos i have yet to decide which gynae to go to. i went to pharmacy to buy folic acid and is 5mg 🤣 can i know the recommended dosage for folic acid ? did i buy a wrong one ? or i have to consume multiple pills instead of just 1 pill a day? #folicacid #1sttime_mommy #cluelessme
