I actually know someone who did'nt know she was pregnant.We go to the same Church.It was her 1st kid.She was told that she could not get pregnant because she had a condition that prevents that.We'll,What a surprise.She was at a company picnic with her husband.She thought she wet her pants,she did'nt.When they both called their parents of coarse they did not believe either one of them.She did'nt babysit as a teenager either.She said she learned quick( even how to change a diaper).There was an 'emergancy' baby shower at Church a few days later.
