Vitamins during TWW

Amanda • Mom of two girls💕 #3 🌈 EDD 12/29/19

Question- I had a MC in late Aug 2018 and my husband and i have been ttc since early September and currently in our TWW. I recently read a post where someone who also recently MC listed their daily vitamins as they took beside folic acid. Not sure but though B12 was one of them. Any advise is welcomed!
