In most places if she is married that child is LEGALLY her husband's child. Until the child is born and DNA is performed you have no rights. Yes, she can go anywhere she wants to go - that would also be the same if you were married to her.

Without knowing which Country you are in "we" are all guessing.

Sorry I am in the uk east midlands
