It sounds like this woman may suffer from schizophrenia and ptsd if she is seeing demons etc. It sounds like she struggles with paranoid dellusions or possibly experiences some psychosis too. Thing is that certain medications used to treat these possible conditions can have a bad affect on the unborn child where it can develop some big challenges if it survives the pregnancy. She has already had one child taken away from her? That's not good and you don't even know if that child was born with special needs or not either.

I think this experience is going to teach you some very important lessons. If she is pregnant then she was not taking any contreceptives and you did not wear any protection either. Any time you don't wear protection you are taking a huge risk.
