If you are underage and pregnant by a boy over 16 will he go to jail if your parents and you do not want him to?

Depends on the state, and your age. * Factors that determine legal action that can be taken relating to such adult a relationship depends largely upon the AOC laws in the state where the parties reside. In some cases age discrepancy, the older person being in a position of authority(coach, teacher, counselor, etc.), alcohol, illegal substances, pornography, and so forth played a part they can be considered contributing factors and increase the odds of the adult or older person being charged. Please be advised, all US states reserve the right to charge and prosecute any adult who violates laws pertaining to minor and adult relationships without the cooperation of the minor, the minor's parents or legal guardian.
