it's pregnant.
that's too bad that your boyfriend broke up with you, either a. he'll come back to you because he's just scared right now, or b. he won't and you should be glad because you don't need someone like that in your life if that's how he's going to be.
i understand that you're scared, but the sooner you get it out, the better. you could write your parents a letter or an email and tell them what's going, or you could tell them in person, whichever you decide good luck.
getting pregnant does sound scary, but it is not the end of the world. there are a lot of young girls on here who have gotten pregnant at the age of 13 and 14 and 15 and they're making it just fine, i'm sure in a few weeks/months after you tell your parents you'll feel a lot better.
i added you to aim, i'll im you if i see you on sometime.
good luck!
