Netix- I have a blood card in my wallet that i was sent out after I had my blood tested and found out I was Onegative.

Rosehip Fairy- For your first child you dont need to have the anti d shot until straight after the pregnancy or a miscarriage. It was probably pushed on you after your first child as this will protect future children who may have rhesus positive blood from being attacked by your body. You wouldnt have had antibodies in your system in your first pregnancy as your body didnt recognise the baby as being something foreign (it only does this when your bloods are mixed which can be if you have a bleed or a bump and at birth). Your doctor was just trying to protect any furture pregancys you may have. He should have explained this to you though.
