I completely agree, Worstfriend. Having walked down that road for five years now I am definitely the odd one out because I figure once I get pregnant I have no reason not to believe it will go well. Very few women in my position are so optimistic, and those of us that are so are viewed as being a bit reckless.
Quick example: my sis-in-law went through a fairly lengthy series of treatments and then fell pregnant by surprise, but because of all she'd been through she had a really difficult time believing her body was capable of going into labor. Didn't help when she did the perfectly normal first time mama trick of going all the way to 41 weeks 1 day. She went into the hospital for som cervidil, expecting to start pitocin the next morning, but ended up going immediately into active labor and 4 hours later had my niece. Sounds like her "defective" body didn't really need help after all, but she still believes she wouldn't have gone into labor without at least the cervidil. She's pregnant again now (another miracle - seriously, this shouldn't be physically possible for her and we are all thrilled!) and hoping to get things started on her own, but not exactly confident.
