Dear one,
You have to realize that you are not at a very good decision making period of your life right now, and yet the decisions you make still affect the rest of your life. Keeping that child won't benefit you, your boyfriend (whom you shuld dump immediately), nor the child you possibly but not certainly have in you ( you have to ask a doctor ).
I tell you this from the bottom of my heart. Whatever you think you are getting into by having a child at your age ... IT IS TOTALLY DIFFERENT THAN WHAT YOU ARE THINKING. Don't do it. You will be much happier down the road when you have gone to college, found a real husband who can support you and a FUTURE child the way it is supposed to happen, etc.
Do NOT abort your future -- your future child, husband, social life, college life, business life, etc. You have a right to grow up, learn, and be who you can be in the future.
You cannot face this alone. Get your mother and father informed so they can help you asses the situation.
One more thing dear one. Your mom and dad won't be around forever. You only have a short period of time in your life to make it like you want it to be. I would take that option now and save the child bearing years for later in life.
Sorry to hear your troubles.
Not everyone will agree with what I said here. But, I don't need everyone to agree with me. And neither do you.
