errr..folic acid is not english medicine. Folic acid can be found in those green leafy vegetables. Thus, actually if you always eat A LOT of green leafy vegetables EVERYDAY, you don't need to take folic acid supplement.
however usually our diet is not so good, thus we are advised to take the supplements.
I also had a m/c early last year. I took the EYS brand once the bleeding stop. But I only took abt 3 bottles (in a gap of 3-4days each time). In the meantime, during that time, I still continued taking 1x folic acid tablet.
During my TTCing days, I take daily 1x folic acid.
and every mth, immediately after my menses ended, I take 1 bottle of EYS baifongwan and 3days later i take another bottle. After that, NO more until the next cycle.
baifoongwan cannot be taken everyday.
