BW- It could be psychological, I was feeling nauseous for ages and thirsty and had diohhrea (sp?) the morning of the transfer, all now which have disappeared (except the thirst). Hope this is the case for you and that a good dinner has settled it down for you.
EJE- Hope you start to feel better soon hun, that morning sickness feeling is awful isn't it? Good to know I'm not the only paranoid one! Thank goodness for the internet!
Smudge- I asked my Dr too, she explained it like this: the uterus is not like a space where the embryo floats around, it is more like 2 pieces of bread with marjarine sticking them together, and the embryo is stuck between the bread and therefore can fall out.....still didn't stop me from trying to keep it in though!
Re: implantation, I think it happens around day 6 (but can be from day 3-12). Someone else may be able to clarify this.
sonya- Hope AF (Auntie Flo) arrives soon !

Hi BG, Nic, Mel and everyone else!
