BCOMPLEX for preggy

Hello mga mommy! Im 23 weeks preggy and currently preparing for Licensure Examination Teachers. Ask ko lang if safe ba ang Bcomplex for preggy. Yun kasi ang suggestion samin ng aming proctor. Nag woworry kasi ako na baka may side effect sya kay baby. Wala naman po akong ibang matanungan dahil di nag rereply ob ko and halos kaka tapos lang ng check up namin. And next month pa ulit susunod naming check up. Bago mag suggest si proctor. Thank you po sa sasagot.
