I need to know what rights to dr visits and so forth I have before the child is born. I also need to know what I need to do legelly to ensure is have parental rights once the child is born.

You have no rights - I assume you are not married to the mother - until and unless the Court (or the mother) GIVES you those rights.

You need to go to Family Court (or the Court that handles these matters in your jurisdiction) and file for visitation (or custody, if she is unfit). They may or may not do DNA testing. She will ask for child support.

You have no rights before the child is born and the mother does not have to take you to appointments with her OR allow you in the delivery room.
