Can you get in trouble if you get a 16 year old pregnant and i am 21?

YES. Course you can get in "trouble"..you are an adult...and she is a minor...legally you can get in alot of trouble...and as far as it goes for your parents...that's a completely different story....help her out though..it's VERY hard to be a single mother when 16...you have to help her though...be there for her...support her.
