“The thing I want more than anything else? I want to have children. I used to feel for every child I had, I would adopt another.”
Sadly, Marilyn could not have children due to chronic endometriosis. It is said she miscarried during the making of The Prince and the Showgirl in 1956, however there is no official record that states this other than Colin Clark and Berniece Miracle (her half-sister) stating that Marilyn had contacted her saying that her “heart is broken” and that she “will try again”. She had an ectopic pregnancy in August 1957. Marilyn then miscarried in 1958 after 3 months of pregnancy.
Marilyn was told in 1959, after having an operation to correct her issues with conceiving, that she would never be able to have children.
