Hello girls! I wanted to ask what vitamins I should start taking? I'm 3-4 weeks pregnant. Elevit or Femibion? I ordered a vitamin complex for pregnant women through iHerb but I'm afraid to drink it because of my first trimester. I'm very worried because this is my second pregnancy. On my first pregnancy, during the first screening, my baby was diagnosed with holoprosencephalitis.
