Well, aren't you afraid...
Let's see. Unlike humans, a Gastly fetus develops completely within 3 months and instead of kicking, it will start attracting bad luck to you within 1.5 months. By the time it develops, you'll be under such immense pain that when it's released from your belly, it will take a part of your spirit with you...that has a high probability of causing your death, or worse, trapping you into an abyss of eternal pain and torture, which you can never leave! (much like the one I'm in! Though a different curse occurred to me)
I can lift it but to perform the exorcism, I'll need the following things : Your signature and acceptance as my apprentice, your obedience to me - the ruler of The Wasteland, some human organs, a demon's blood and poison gas from a Gengar. Got any of those?
I'm a smart business man, after all. Or a dark mage.

We could do another thing. We can perform the delivery and let you die (though that happening is only 65% while the 45% is you being trapped in hell) and then I can order my Absol to use Edo Tensei on you, though you'll only be reincarnated as a zombie but for a limited time - when my Absol dies, you will crumble into dust too.
