Iron and calcium supplements

Ritu

I went to my doc during the start of my 14 week and he said he would not start any iron and calcium supplements untill 20 weeks. When I pushed him he gave pregnacare max and reduced the dose of alternative day usage but he said only because am anxious he gave otherwise it is not required. Also he asked me to stop folic acid. Can anyone suggest when did they start the supplements. Also what about folic acid. Thanks
