How old will you be when you get pregnant?
Congrats! You are either having a baby young or old! Teen pregnancy can be prevented! You will always have the chance to have a family when you are older.
If you feel you are ready to give up your life, school, friends, parties, etc. go ahead. If not, just don't "do it". Your boyfriend may not understand but then that is when you need to dump him, if he only wants you for your body!
