Millions are getting birth control advice from TikTok. Experts warn the consequences of getting it wrong have never been more dangerous in post-Roe America

Millions are turning to TikTok for advice on preventing pregnancy without hormonal interventions like the pill—but the social platform is rife with misinformation and experts are warning that it's an especially dangerous moment for American women to take birth control advice from unvetted sources.

Interest in content that discusses fertility awareness methods (FAMs) of birth control—techniques that avoid unplanned pregnancies by abstaining from sex or using other forms of contraception around the time of ovulation—has soared on TikTok, with search terms associated with FAMs scoring millions of clicks on the site.

The boom in interest worries many reproductive care experts, however, who say that after the Supreme Court’s recent overturning of Roe v. Wade, the landmark ruling that made abortion access a constitutional right, women who turn to social media are putting their health at even more risk than in earlier times.

With individual states now able to further restrict abortion access, the concern is that women who don’t receive correct information on FAMs could end up inadvertently falling pregnant and being forced to carry to term.

“Speak to someone who is well versed in reproductive health, and that is obviously not an influencer on TikTok,” said Kimberly McFerron, head of birth work at pregnancy and women’s telehealth clinic Ruth Health. "With how threatened reproductive rights are here in the U.S., [getting FAMs wrong] becomes an astronomical issue very, very quickly.”

Using FAMs

Unlike hormonal birth control—which has been linked to side effects like acne, headaches and weight gain—FAMs have no physical side effects.

There are three main ways women who opt to use FAMs can track their ovulation, according to Planned Parenthood: recording their body temperature every morning before getting out of bed, monitoring their cervical mucus, and tracking their menstrual cycle.

Generally, medical practitioners advise that two or more of these methods should be used in conjunction with one another to increase efficacy. When multiple FAMs are combined, it is called the symptothermal method.

According to the British National Health Service (NHS), if natural family planning is followed “consistently and correctly,” it can be up to 99% effective.

However, Planned Parenthood says that typically, FAMs are only around 76% to 88% effective, meaning 12 to 24 couples out of every 100 using an FAM will get pregnant each year.

“The better you are about using FAMs the right way—tracking your fertility signs daily and avoiding sex or using birth control on ‘unsafe’ days—the more effective they’ll be,” the organization advises. “But there’s a chance that you’ll still get pregnant, even if you always use them perfectly.”
