*Cynthia Williams is suing her doctor for a pregnancy she says never should have happened.
Williams, 40, and her husband, both carry the sickle cell trait and after having two kids – each born with sickle cell – the two decided against having more.
The sickle cell trait is a genetic abnormality that has the risk of causing a dangerous blood disorder in the future children of the affected parentage.
Cynthia thought she took the necessary precautions to ensure against future pregnancy; using the rhythm method of birth control. But in spite of this, her third child was born. The couple knew there was a 25 percent chance that the baby would have sickle cell disease, so they were relieved when she was born a carrier instead.
Back to birth control. This time, Cynthia tried taking the pill, but high blood pressure made it necessary for her to seek out more permanent measures; so she got her tubes tied. That should do it, right?
She would soon learn otherwise…
“At that point, I just wanted to get my tubes tied,” Williams said. She had the sterilization surgery in December 2008. But six months later, she was staring at the sonogram in disbelief.
How could this happen, she wondered.
With only one ovary (she lost her right ovary to a cyst when she was 12) she believed she couldn’t get pregnant because the tube tethering it to her womb had been tied.
“I was livid,” Williams said, recalling the “impossible” blue line on the pregnancy test, quickly confirmed by the flutter of a heartbeat on a sonogram.
“I just lost it.”
Her fourth child, Kennadi, was born in February 2010 with sickle cell disease.
Now the Williams’ are suing Dr. Byron Rosner of Reproductive Health Associates, for “wrongful pregnancy,” claiming that he “failed to perform an adequate or appropriate tubal ligation,” resulting in an unplanned pregnancy and the birth of a sick child, according to the lawsuit.
Without a right ovary, Williams only needed her left Fallopian tube tied. But Rosner “tied,” “excised” and “cauterized” Williams’ right tube, according to medical records obtained by ABCNews.com.
Cynthia’s other children are grown, ages 25, 21 and 17. Williams, now 44, can’t believe she is raising a 4-year-old toddler.
“I love Kennadi with all my heart, and that’s the honest-to-God truth,” she said. “But it’s been a life change for everybody –- my whole family.”
