Wow. I'm getting "The procedure" in a couple of weeks, because I just don't want the same thing to happen to me.
I can't tell you how many people I have met through the years that while their bodies were just about in the throws of menapause they got preggers.
Throwing out the high chair...yep, that was not a good idea. I gave all my stuff away a few years ago. However, it was too several other moms in my moms group and if the same thing were to happen to me, they'd all be lining up to give back and then some.
Generally, it seems that those things, when positive, are usually right. When I was pregnant with my son, it said negative for weeks and weeks and doctor even gave me something to bring my period on, because his test said negative too, but I was definitely in bloom.
