so sorry for MIL stupid comments ! My MIL said something similar, " atleast you did end up with a retard" "your body was just fixing a mistake... Oh not in the baby, genetics!....) and step MIL the worst....... when she asked me how I was feeling.....
I absent mindedly said " like I'm dying" to which the evil ***** replied " you are not the one Who is dying !!!! "

hope you have lots of support from your hubby as you go through this
