Hi Carolyn,
Congratulations on twins! Wow! Glad to hear all is well!
gigi & poohgirl - welcome back and all the best with your upcoming cycles!!
Hopeful, when is your next scan?
chriss, JDC, JenB, kelly - hope all is well!
sabi - hope you are having a wonderful time away!
I think you have to go with your gut feeling about what to say if someone should ask, did you use IVF - and it sounds like you did just that.
Our doctor encouraged us to have something to say, should we find ourselves in that situation. Here in Germany, no one has outright asked and we haven't offered any information other than to say we were very surprised to find out we were pregnant (which we of course were, after so many disappointments!).
My mother, on the other hand, fully expected people (friends, family acquaintances) to ask if we had had IVF, because she said so many of her friends children have gone through it there (in the US) -- We told her, if they asked, then it was fine to say that we did get pregnant through IVF - if they don't ask, she doesn't have to say anything --
I think I would also be totally taken aback if someone asked me outright if we used IVF and would have probably answered just as you did!! So far, none of my friends in the US have even asked, just friends of my mother -- funny, isn't it? Then again, no one even knew we were trying, and then we announced that we were pregnant -- Actually, we only said we were expanding our house by 2 feet in October, but everyone got the idea...
Take good care, everyone!
