Quoting mellie98:" The father won't be around I don't think"
Unfortunately, it happens at your age. Just concentrate on taking care of yourself and your baby and when the baby is born, file for child support. Even if he isn't around, he still has to help out financially and such. (Maybe not at first, his parents may be required to pay it, but give it until he gets a job, then he will be made to pay).
But even if you were older, it still happens, I was 18 and it happened to me, too. My sons father is not in the picture, he hasn't seen him since he was 3 months old and my son is going to be 4 and starting preschool in the spring. His father still has to pay and buy him medical insurance.
