Recommendations for Folic Acid and vitamins please

Hello. I just had a miscarriage and needed to perform D&C last Jan 25, 2020. We really do want to have a baby again. Was advised by my OB na magtake ng Folic Acid come March. Any recommendations ng Folic Acid/Folate na pwede ko inumin? Yung affordable. Also, may any ba din po kayo marecommend para magbuntis ulit? May any additional vitamins po ba ako need itake? Currently, I'm taking Sangobion and Be Well C plus Calcium. Thank you so much. ???
