So I was watching tv right...

and I saw this commercial for this tv show called "I didn't know I was pregnant." Now I'm kinda wondering, how many times in a year does this actually happen? I mean I've heard a bunch of stories but I didn't know that there was enough of these incidents that can make a series of tv shows. So would it be like a bunch of stories from years ago? Or are they recent stories? Who knows? All I know is that I might watch one episode and will never watch another one. Suck on that TLC..
