Ok so there is this movie that I can't figure out what it is. A woman on earth is unable to have babies, so she gets pregnant and its because of a male race from another planet that is dying or something. One of their males comes to protect her and keeps giving her these special pills while she is pregnant. They are trying to make it to this place where his spaceship is going to pick him and the baby up but they are being followed by an evil male alien. At the end she gives the baby over to the good guys and they tell her that she can now have babies.

Sounds like Starman
