I'm Sorry...But How Can There Be A Show Called "I Didn't Know I Was Pregnant?"

I have seen this show numerous times and I still can't believe that A) the show even exists and B) there are enough women who didn't know they were pregnant to make an actual regular series out of it. When I was pregnant, I looked like Kate Gosselin despite only having one fetus in my womb. I also had the pukes and it tasted like someone took a dump in my mouth for nine months. Oh yeah, and I stopped getting my period. How can someone not know they are pregnant?? Maybe I'm just jealous. :)
