I couldn't take them at all. Made me quite sick. Was advised folic acid and plenty of fresh foods/ good diet and now im 25 weeks vitamin d. Hope this helps
Is important you take folic acid and Iron for you and your baby, folic acid is what helps with the development of your little one
My doctor told me not to take mine tell he says it's okay, just make sure you eat enough food rich in vitamins and nutriants.
