There’s a Pill Between Plan B and Abortion That ‘Treats’ a Missed Period
Menstrual regulation with period pills could let us think of ourselves as "a little bit pregnant," as a new episode of the podcast Invisibilia explores.
In Depth

A late period ratchets up the anxiety. You could be pregnant. You need to hunt down a pregnancy test. You might have to consider ending a pregnancy. But as Invisibilia producer Abby Wendle suggests in the NPR podcast’s latest episode “A Little Bit Pregnant,” this doesn’t have to be the case, especially for those who don’t want to be pregnant. The episode’s “thought experiment” asks: What if, when you miss your period, you can be prescribed a pill to bring it back without having to cross your fingers and pee on a stick?
Falling somewhere between emergency contraception like Plan B and abortion as most people think about it, the period pill—also called “missed period pill” or “late period pill”—is a way for individuals to treat the symptom of a missed period without necessarily having to grapple with the question of whether a pregnancy caused it. As the podcast makes clear, it’s an abortion pill (typically misoprostol alone, or with mifepristone) but rebranded; you don’t need a positive pregnancy test to feel justified in taking it.
For the episode, Wendle spoke to a number of experts seeking to reframe how we think about pregnancy and abortion. They included Dr. Wendy Sheldon and Cari Sietstra, who are part of the National Working Group on Period Pills—a group of nearly two dozen collaborators trying to introduce period pills into our fertility control options, Sheldon said. This type of menstrual regulation (MR) is regularly used across the world, in places like Bangladesh, Indonesia, Myanmar, India, Cuba, and Brazil (some of which have restrictive abortion laws), Wendle reported. MR was historically practiced in the U.S. by midwives using herbs and tinctures. But the group’s attempt to reintroduce it via pills has prompted skepticism from many—including from those who work in reproductive health.
“If you are in a situation where you want to value your reproductive freedom over knowing for certain…then that ambiguity is very valuable.”
Especially in a post-Roe America, there is the sense that period pills could further exacerbate the stigma surrounding abortion, allowing people to skirt the issue of abortion entirely instead of actively fighting to protect access to it. Sietstra said that at a conference where Sheldon was presenting, an influential abortion rights funder shut her proposition down by saying, “Period pills? Good luck with that!” before walking away.
