Dozens of countries around the world already let women pick up birth control pills without a prescription.
But in the U.S., a prescription from a doctor is required in almost every state. There are benefits, like professional advice on which type of birth control method is right — the pill or an intrauterine device — and doctors can offer oversight if there are side effects or if a rare disorder is discovered after a woman goes on the pill.
But those who want to make a birth control pill more accessible ask: What happens if a woman runs out over the weekend or if going to a doctor means a three-month wait?
Of course, there are plenty of birth control pill options. Some advocates say getting a progestin-only OTC pill onto shelves would be a tested, safe first step.
A 2013 survey showed just over 62 percent of women in the U.S. surveyed thought OTC oral contraceptives were a good idea.
Two big reasons? Convenience and privacy, according to a 2016 study.
OTC birth control could make it more convenient for women in regions considered "contraceptive deserts" — meaning there are no public clinics or sites offering birth control.
One of those states is California. But a study showed not many pharmacies there are offering the service and that for more than half of those that do offer it, they charge up to $45.
The app Nurx is another "workaround." In select states, women can order and get birth control delivered through the company. Doctors then review and virtually approve order requests.
Some insurance plans cover Nurx products, and the brand claims it will find options that "won't break the bank" for women who don't have insurance.
Let's talk about cost. A 2015 study found there could be public cost-savings if low-income women could get birth control without a prescription, decreasing the number of unplanned pregnancies. This study emphasizes that pills would need to be inexpensive.
So this all sounds pretty feasible. Then why isn't it a thing in the U.S.?
That's largely because U.S. company Ibis Reproductive Health had just partnered up with Paris-based HRA Pharma. When announced, the plan would first research the drug and then apply with the Food and Drug Administration to make an OTC birth control pill.
At the end of 2017, an update from the companies said such a product for the U.S. was still being researched. That partnership wanted to not only make OTC birth control available — but it also wanted insurance plans to cover the cost.
A survey published in October 2016 found adults and teens were more interested in the idea of an OTC progestin pill if their insurance covered it.
But insurance coverage for the pill isn't a given — and that's when it starts getting a bit more political.
On the federal level, President Donald Trump recently dismantled a part of the Affordable Care Act that didn't let employers opt out of covering birth control costs. But Democratic attorneys general from several states said that wasn't constitutional. And in December, one federal judge temporarily blocked Trump's decision.
If OTC birth control is a thing someday, a mandate, like Trump's, might determine if insurance covers it.
Some states are trying to keep Obama-era-style coverage intact, regardless of what goes down on the federal level.
Plenty in the GOP have supported the idea of legislation for OTC birth control. But that Republican support often comes with a few caveats — like separating birth control from insurance coverage or an age requirement for buying over-the-counter birth control. And some GOP senators support OTC only if shoppers are over 18.
Birth control advocates and some Democrats say OTC birth control wouldn't be accessible if young women legally can't buy it or if insurance plans don't knock down the cost.
So what's next? Well, it's a little hard to say.
While bipartisan support isn't the only ingredient needed to get birth control on the shelf, it certainly is a major factor in the OTC fight.
