Fleur, that's so crazy that it's worked out so well and so quickly for so many of your friends like that! Lucky ducks! My bff is one of those crazy ones who got a "surprise!" pregnancy. She must be super fertile, I swear. She was terrible about ever remembering to take a pill so she was using something else (I can't remember what but I think it was a diaphragm). Well she messed it up one time and surprise! Thankfully her and her husband (although definitely surprised) were in a place to be able to be happy about a 2nd child, the timing between the two was good, etc. He got a vasectomy after that since she can't really be trusted with it.
Just funny though, how ONE mistake in bc can cause that with some, while others like us try and try, around the "right" times of the month with no protection, and nothing. Ugh!
I'm also glad you got your hands on a kit and your lucky pregnancy test! I agree that it will bring luck to you.
