Hi all, I had my 16 week midwife appt this week and was told that I didn't need a blood test as it was to check for down's and wouldn't be accurate as I'm having twins. I didn't think much more of it, but now I'm thinking that can't be all it's for. Surely they need to check for all the normal things too, like iron etc? I'm not very happy with my midwife as she's not great on the reassurance front, seems to take the easy route for everything, and has given me no extra information considering I'm having twins. Grrrrrr!
