there really is no way of determining who the father is just by how far along a doctor tells you you are. They are wrong sometimes, and the only way to be sure is to have a dna test done after the baby is born. I don't fully understand why it would matter who the father is if you want to give it up for adoption or not. A baby is a baby, and you're going to love it no matter who the daddy is. Just be careful with the choices you make. Be sure you wont regret them later in life when it's too late. If you need help with anything you can
pm me.
