What can I do if I’m still pregnant and wish to leave the state without the father’s permission?

The father has no say until the baby is actually born. You are free to move now . . . but will not be once the child is born.

I've recently researched an litigated this subject. No, you have been misinformed. A pregnant woman has a Constitutional right to go wherever she wants, and no "permission" by anyone is relevant or required. Jurisdiction as to custody does not attach until a child is born - and is present at the place where the baby is born.
