What supplements did your docs suggest? We are at 7w3d and still seeing our assisted reproduction OBGYN until 12w, and his office runs like a machine, so we're not getting much feedback on how to care for a twin pregnancy. We have identicals (not yet sure if mo/mo or mo/di). We ordered "the" what to expect book on multiples from Amazon and started extra folic acid, but would really like to hear what medical professionals are telling their patients about things like iron, calcium, magnesium, vitamin D, fish oil, etc. Thanks in advance!!
