Forcing to marry young?

Hi my name is Kari, im new on yahoo answers and i am hoping to seek advice. My parents have grown up with it in mind that I am going to get married and have children young. Them with a bunch of other families are planning on the same thing. I find it really strange because I am only 16 and they are wanting me to have unprotected with my "future" husband and i just dont understand why they want it. My parents where set up to be married as well so maybe they feel that have too, also it is a family way of doing things. But now i may be pregnant and part of me wants to terminate it if i am because one they find out they will get their way which i dont comepletely want. I just dont know what to do at thi point because i feel that i have to follow their way of life, and i am suppose to get married in march. ohh that joys, i get upset when i read other teens wanting to have children and getting married, because let me tell you if you where being forced it is a whole differetn feeling and life. Please if you have any advice do share.
