Yeh. One of my friends at school had a baby and she had no idea she was pregnant. She didn't really put alot of weight on and had no idea until one night she felt Ill and someone called an ambulance and and the paramedics told her she was having a baby! Everyone was shocked..so it does happen.
I thought 7 months seems a long time but I'm kind of glad in a way...its not going to drag on as a storyline
