Mommies, do you think?

That all of these questions on here about "help! I am 14 and pregnant!" or "Could I be pregnant" etc. are real, or are these just kids playing around? I have been a regular to this forum since I found out I was pregnant, and I have noticed a ton of questions such as these..additionally, if they are real, then we must have a HUGE epidemic of young girls getting pregnant...is this not disturbing all the way around?
