Yes you're right cbeebies and I know it which is why I felt so guilty. But emotions are funny things that don't respond to logical reasoning, and it don't think it helped that I'd been awake since 5am due to pg bladder and hormones! Feeling much more in perspective now, today I am pregnant and very grateful for it 
Thanks for your kind words medusa, I think you hit the nail right on the head there!
I'm going to Dublin for a three day conference tomorrow. A bit nervous about flying, both because of the small risk and because I don't want to be sick on the plane! On the plus side though, if I'm not ill then I can steal the sick bag for emergencies
. The antibiotic excuse that I got from the lovely ladies on here will be coming out again, there's no way I can avoid the Irish alcohol for three days otherwise!
