Perri made this known during a question and answer session with her fans on Instagram.
Recall that the 30 year old retired athlete posted a video to announce that she was expecting a child. In the video, she said her pregnancy came as a surprise because she never thought she could have a child.
When a fan asked why she thought she could not have a child, Perri replied saying she got scared that she had tampered with her reproductive system due to the use of birth control pills over a long period of time.
