This afternoon I got the result of testing for my blood group. It's O, which is excellent news since that group is compatible with all other blood groups. So, no matter what Jamie's group, we'll be ok.
I phoned Suzanne to let her know but she's on holiday until Monday. I left a message though and I've no doubt she'll get back to me. In the meantime, I'll pick up a printed report from my GP surgery tomorrow and will email it to her.
Needless to say, I've already let Jamie know that little piece of good news.
