question: Hello doctor, I have Crohn's disease and am pregnant. The first day of my last period was before 40 days and I have been taking multivitamins which includes 400 micrograms of Folic acid for the past four months. I am now pregnant. The doctor said that I need 5 mg of Folic acid due to the Crohns which I have started from today. No one told me I need more Folic acid than average woman until today and I am now sick with worry. If I had been taking an insufficient amount of Folic acid and caused harm to the baby, then how or when will I know?
