Ha. Carry them round. Unlikely.
I don't have any at the moment as the UCH ones were sent back after I moved house and I haven't been provided with new ones yet by the new midwife.
Heaven forbid I go into early labour and shock, horror, the hospital don't have my blood results.
I think it's a good idea to know what in your notes, but unless there is a potentially serious complication in them, I can't really see the point in dragging them round and thus risk losing them before your EDD.
Can you imagine going to a wedding whilst pregnant (I've been to two so far) and having to bring a Tesco carrier containing your notes becuase they didn't fit in your fancy handbag.
