folic acid & other supplement(s)

Hi Mummies, im new here. Im 8 weeks pregnant and have not taken folic acid yet. Met doc yest and plan to take it today. 1) Just wondering if it is too late to start now? 2) Does anything bad happen to the baby for not taking folic acidq earlier? 3) And what other supplement is good and recommended for pregnancy and baby? Thanks in adv.
