Here are quotes of her interview from MSNBC, no where does it say 'Monster'.
During her first marriage, Heinz Kerry said she wanted a fourth child after the birth of her son Christopher in March 1973. She said she had a “severe reaction to something,” was taking heavy cortisone medicine and did not realize she was pregnant.
“I told my doctor I think I’m pregnant and ... he said well then if you’re pregnant, you have to abort that baby ... and I was very upset ... I didn’t want to have an abortion, but they gave me 15 days because it was early and the night before I was due to go in, I miscarried it. So God was very kind,” she said.
