Appearing on Thursday's "Dr. Drew" show, she said fertility doctor Michael Kamrava had handed her a note about what she would do if "too many [embryos] grew."
"He gave it to me to sign right there while I'm laying down and I signed it and didn't read it," Suleman said, CNN reported.
Kamrava had his California medical license suspended July 1 for gross negligence, KABC-TV, Los Angeles, reported. The California Medical Board ruled Kamrava "did not exercise sound judgment" when he transferred the 12 embryos in 2008.
Suleman, 36. said she never intended to have eight children in January 2009 in addition to the six she already had.
The single mother living on public assistance conceived all 14 children through in vitro fertilization.
Suleiman said she had been turned into a "parody without permission."
"I have the spotlight. I know it's my responsibility [for my kids] to brush it away and get rid of the Octomom character," she said.
Suleman said she suffers anxiety, panic attacks, hyperactivity and obsessive compulsive disorder and was taking a "cocktail of drugs," including Valium.
