Just had some more bloods taken, checked my maternity book and was a little confused as to what they were testing for at 16 weeks as I had the serum tests done at my first scan at 13 weeks and received a letter saying no  further tests required. The nurse taking my blood said it was a repeat test but didn't say what for. When she was filling in my book I asked if she could tell me my blood group. Turns out she can't because this lot of bloods is a repeat grouping. My THIRD lot! So annoyed! How can they manage to have already taken 4 vials of blood and not no my bloody group!
