Sara first began to speak about this radical turnabout in her life in October 2015.
"I regret having an abortion and today I'm asking for forgiveness," she wrote on Facebook at that point, almost one month after the birth of her second child. Since her baby was born, she said, "my life has taken on new meaning."
"I don't want you to go through the same thing I did," she told her readers.
Years before, she underwent an abortion using a drug provided by a feminist.
"I almost bled to death and had very serious complications," she recalled, adding that the person who came to her aid in those circumstances was a man who had "no connection to radical feminism."
On abortion, she urged, "feminism should be focusing more on taking care of women instead of putting their lives at risk." She said her prior abortion had caused difficulties early into her second pregnancy.
Sara has also become a critic of transgender ideology. She explained that she has no animus against people who say they are transgender, but she added, "I don't think that changing your clothes, getting silicone breast implants and making the transition with hormones and surgery can change anybody's sex."
By mid-November, Sara was urging Brazilian feminists to "respect women who are religious believers." Although she has no religious affiliation, she said that "one of the things I regret in my life is pulling away from God and devoting all my time to militant feminism."
"Having faith is not a retrogression and other people's religion needs to be respected," she urged.
Sara said that she has faced a hostile reaction from the feminist faction she has abandoned.
"You have no idea of the reprisals I've been a victim of coming from the feminists," she wrote. "I'm afraid of even stepping out on to the street with my baby, but I have faith that all this is going to go away."

In early December last year, Sara published a short digital book about "seven times I was betrayed by the feminist movement." The book is a compilation of the bizarre experiences she says she had as part of the Brazilian feminist movement, involved orgies, alcohol, drugs and misuse of funds.
For every book sold, she has offered to donate a Brazilian Real (about 25 cents) to "initiatives helping women in violent situations and against abortion."
She said the main reason Brazilian people do not like the feminists is because many of them act hysterically and use social media "to mock and humiliate religious people, preach hatred against men, besides being extremists and disrespectful of other people's religious heritage."
"I'm just as guilty. I used to be like that too, but thanks be to God I've been healed," she said.
