Sorry to freak you out, NegNellie. It's been a tough time for many of us over there, and -- like someone else mentioned -- the troubles seem so magnified when a women begins her parenting experience physically, mentally and financially exhausted after years of infertility.
Twins ARE difficult, whether they are OE, DE, whatever. I know several women who had sex with their DH's, got pg, and delivered prematurely. Their kids are just as involved as some of our kids. Dealing with issues is all part of the parenting process, and it's a roll of the dice. Singletons can be just as difficult as multiples. I wish I had a nickle for every woman I've met who has told me the story of the baby they delivered at 25 weeks... NICU, etc.
I agree that the posts on the pink might cause a women to rethink single-embryo vs multiple embryo transfers. But in spite of what I am dealing with now, I would still choose to have my hands full with (complicated) twins than to have gotten a BFN with a single-embryo transfer. My baby will never remember these difficult days, and when I feel like I'm ready to crumble, she gives me the largest smile imaginable. And I remember why I'm here.
Every step of this journey is painful, scary and uncertain. If you want it, you just have to take a leap of faith.
I wish you lots of calm clarity as you move forward. And I do hope all your dreams come true!!
