Thousands of women have shared their experiences of abortion on social media in an attempt to break down stigma.
US abortion activists Amelia Bonow, Lindy West and Kimberly Morrison started the hashtag #ShoutYourAbortion on Friday to allow women to tell their stories.
It came in response to a US House of Representatives vote to defund the women's health organisation Planned Parenthood.
Since then, thousands of women have tweeted the hashtag, with #ShoutYourAbortion trending in the Australia, the United States and Europe.
Hashtag creator Amelia Bonow told Buzzfeed that she had shared her experience of having an abortion on Facebook to "vocally align myself with Planned Parenthood".
But many Twitter users have objected to the women’s posts and and posted pro-life messages under the hashtag.
Others have stated that adoption, not abortion, should be an alternative to an unwanted pregnancy.
