I am 36 weeks pregnant and today saw my midwife (a new one as mine has changed areas) she asked if I had been taking vitamin D throughout the pregnancy (or a pregnancy vitamin) I stopped taking this at 12 weeks because I was told it wasn't needed (by another midwife). The one today said that was probably the folic acid she meant. I have been so worried with risks etc with my pregnancy diabetes/first timer I just doubt I would have stopped without being told but however this misunderstanding has come about I am really worried now. She said not to worry and to start taking it now anyway. Should I be worried?
