When I was a teenager, I remember a friend confiding in me that she
feared she was pregnant. I was a bit shocked because she was so young,
and because she was not involved with anyone of which I was aware. I
asked her why she thought this, and she told me that she had a late
period, and she knew that meant she was going to have a baby. Upon
further questioning, I realized she was still a virgin, and there was
no way she was pregnant. Sadly, this type of misinformation is common
with young girls, and even some who are well into adulthood.
