I have a friend who found out she was 20 weeks pregnant while getting the shot. She started having pain in her side so she went to the doctor. He couldn't find anything wrong with her so he sent her to the hospital for further testing. Ultrasound inidicated she was 20 weeks pregnant... oops. She now has 5 kids of her own (all boys - one set of twins) and is married to a guy with two kids (both boys) of his own. Between them, they share 3 kids (the twins and youngest boy). Her twins were BARELY a year old when she found out she was pregnant again.
