There may be a few (and it's very few) states that would allow this. But under the law you are a minor and your boyfriend is an adult. Most states have laws about 'enticing a minor' 'contributing to the delinquency of minor' 'statutory rape' or something to that effect. If he takes you across state lines to get married, then he could very well be breaking a law. That can't happen without parental consent. He's probably already broken one very big law by having sex with you. There are very few states where 15 would be considered the age of sexual consent. Rather you willing had sex with him or not makes no difference. Rather you're now married or not makes no difference, because the crime took place prior to the marriage. You have probably already pissed your parents off enough by getting pregnant at 15, do you really want to take the chance of pissing them off more? Because if you do, they might decide to call the police and report him. Once that baby is born, there is will be no doubt about his guilt, because aDNA test will prove that he's the father.
If a health care provider knows the father of the baby is 20 and your 15 they are legally obligated to tell the police. It varies from state to state, often (but not always) you can marry without the father getting in trouble if the girl's parents support the marriage. It usually helps if the girl's parents knew about the relationship well before hand and were comfortable with it. For a girl under 18 to marry requires parental consent. The youngest age for a girl to marry with parental consent varies state to state (and has changed with time). Example Michigan: http://courts.co.calhoun.mi.us/quest458.htm Many states will not allow someone under the age of 16 to get married without a court order.
In many states a 15 year old cannot get married, even with parental permission. Yes, it is illegal for a 19 year old to have sex with a 15 year old in. If the state will allow it, it typically requires a doctor's certification and a court order.
