"This should have never happened and I don't wish this upon anybody," said "Brianna," who doesn't want to be further identified. She spoke at a news conference Thursday.
Brianna, 18, is eight months pregnant, and as she is about to become a mother, she says she found the courage to come forward to help other potential victims.
"The district needs to start doing their job because they're supposed to protect their students, not physically harm them and mentally harm them," said Brianna.
Brianna said that in 2010, when she was 14, she was sexually molested by Andrea Cardosa, who was then her teacher in the Val Verde Unified School District in Perris. She said Cardosa was controlling.
"By convincing my mother that she would do great in my life, she turned my mind against thinking that all I needed was her," said Brianna. "There was lots of manipulation within the time."
Brianna saw a YouTube video released last week in which another alleged victim named "Jamie" confronts Cardosa on the phone.
Jamie said Cardosa had sexually abused her for years beginning when Jamie was a 12-year-old student at Chemawa Middle School in Riverside. Jamie said that in 1999 Cardosa was a coach at Chemawa Middle School in the Riverside Unified School District. At around that time Cardosa resigned, but officials won't say why because of the pending investigation.
Brianna's attorney, Luis Carrillo, filed lawsuits against the two school districts on Wednesday.
"[The Riverside] district ignored it, gave a positive recommendation to Ms. Cardosa and then she got a new job at Val Verde Unified School District, where she committed other acts," said Carrillo.
The Val Verde Unified School District said in a statement: "We continue to cooperate with law enforcement and the investigation but with the pending litigation we can't comment any further."
Brianna is scheduled to meet with Riverside detectives Friday as they begin their investigation of this case.
Cardosa has not been charged with any crime.
