Earlier this week, Toronto college student Rupi Kaur posted this photo to her Instagram account.
The next day, Instagram removed the photo, claiming it violated the company's Community Guidelines.
It's from a photo series Kaur created with her sister as a final project for a college course. The project is meant to "demystify the period and make something that is innate 'normal.'"
After the photo was removed, Kaur reposted it, pointing out that it does not violate Instagram's stated guidelines.
The guidelines state that users are prohibited from sharing content that: belongs to someone else, shows nudity, mature, or illegal content, or promotes or glorifies self-harm, none of which Kaur believes her photo did.
