Hi, I am 5 weeks today and I have been eating very well along with taking 1mg of folic acid everyday. How important would you think it would be to take a prenatal vitamin ? Has anyone gone through the 1st trimester without taking a prenatal vitamin and only started to take one when they were about to enter their 2nd trimester ? My doctor told me 1st trimester would be fine without taking a vitamin and 2nd trimester is where more vitamins are needed for the baby.. I would like to know others experiences. Thank you!
