I think I know what you mean. A lot of us were "accidents" lol, probably more than you realize. You aren't alone. How you came into the world doesn't matter, it doesn't define you. All that matters is that you're here now, and your life is your own to make something of. You matter.
Also, there's nothing wrong with questioning these things that bother you, and trying to work through them. It's good to process them and come to terms with them if you can. It's okay to ask for help if you need it, too. But please be kind to yourself, as well.
The US is a raging shit heap at the moment, but it's normal to have multiple sons here. Even if it wasn't the norm though, or even against the law (which is so bizarre to me), you have every right to exist. You don't owe anyone anything for being born, and you do not need anyone's approval to exist.
We've all agreed to pitch in and buy you ear buds for Christmas.
