thanx, and say i was, how do i tell my mom?
should i?
YES. If you are pregnant then yes.
All round YES. You should definitely tell your mother, no matter what decision you may come to (abortion/adoption/keeping the baby). It is important that you and the baby are looked after properly and get the medical attention you need, you will struggle to get that without your mother's help at your age.
She may be angry, she may get cross but I tell you what, you are her daughter. She loves you. No matter how upset she may be at your decision, she will be there to support you.
I was so scared when I found out I was pregnant, so upset, the only person who knew was my boyfriend, I was stressed out and that alone was making me feel even worse than the pregnancy. Eventually I told my mother, after 2 weeks of knowing I was pregnant, and booking an appointment for an abortion. She came with me and she stood by me, she helped me through it, even though I was terrified at the thought of being put to sleep (for the abortion). She was upset that I had become pregnant at 18 but she supported my decision and she looked after me.
As for ways of telling her, don't do what I did. I ran into her bedroom, burst into tears and the whole sorry story came tumbling out in a mashed-up fountain of words. Plan it out first, if you cannot face telling her face to face (which is always the best option), you may want to write a letter, explain your situation, what you plan to do and any ideas on how you could go about your decision (pamphlets on abortion/adoption/some knowledge of the costs involved in raising a baby & how you would continue at school). If you show her that you are mature enough to think about what you are going to do she will appreciate it more than you walking up to her saying "I'm preggo n I'm gunna keep da baby".
