Hi sir, I am known to have PCOD. while trying to conceive I was prescribed Corectia tablet. this seems to have minerals, B12 and D3 but did not see it mentioning folic acid /B9 which now I found is very crucial while planning and during pregnancy. I was then prescribed FOL123MF right after positive urin test (6th week) and I'm continuing the same since then. I am now on 16th twin pregnancy. I had my NT and dual marker test done which screened low risk. worried about the Folic which I should have cosumed well in advance.please suggest if any risk ahead during anatomy test?
