If your parents know you are sexually active WHY are you asking strangers if you are pregnant if you should have an abortion?
Some 14 yr olds believe their parents don't know much about anything and that they aren't even very smart. And some of them are right. Most 14 yr olds however do have parents who know more than they did when they were 14 and most of them would know how to help their child make life changing decisions better than the average stranger. Unless your parents have totally freaked out because you ARE pregnant, I suggest you have this talk with them.
