You're right, that is a lot to have on your mind! Not that I'd know too much on this topic, but your the way you say you've been feeling lately does sound suspicious. I can't imagine how it will be someday to wait through that unknown period of time where it's too early to tell and you just don't know! I am totally with you on the emetaphobia thing too - I could have nightmares about it it scares me so much. But there are people who never have morning sickness so maybe we'll be lucky enough to be those people.
Well maybe we're jumping ahead of ourselves here, but I guess all I can say is good luck with the waiting and I hope that everything turns out like you want it to
