Dear sister ,Its really heart breaking, when one goes through this situation in life . 
I dont have any experience about this .
But my mother did went through this !!!
And not just 1 and a half years ....
But more than 4 years !!
Even the Doctors said that there is no hope !!
And it was impossible ,
if we look at it in the manner of Science .
The blood group was making the difference ....
The Rhesus blood group combination ,
which my parents have !!
And so my mother after hearing all this ..
she didn't lose hope .
She prayed a lot ....
My whole family prayed regarding this matter ,
and all their prayers were answered ... 
My mother's tears were seen by our Lord ...
and thats why i am here with you all today !! 
My mother have told me that through what all things she had been ....
but JESUS brought her through all that !!
Have hope in HIM .
Have faith and pray ,
believing that HE has given you your desire .
For HIM NOTHING ....... NOTHING
IS IMPOSSIBLE !! 
I'll pray for you .
Lots of love & prayers :
