We know shockingly little about many of the conveniences we rely on in modern life.

The cars we drive, the trains we ride, the smartphones into which we type our most sensitive personal data — for most of us, their inner workings are pure mystery.

The same goes for our birth control. Questions abound about the tiny pills — or patches, or condoms, or intrauterine devices — that we count on to sidestep unwanted pregnancies.

Many women have obsessively Googled questions like these, along with other reproductive health queries.

Google no further. The Lily’s video series, “When Used Correctly,” has answers for you.

Each episode is approximately three minutes. There are seven total — just 21 minutes to binge-watch the bunch.

“YES! We need more of these. I’m a pharmacist and there can never be too much sharing of stories along with data from health care professionals. I got the IUD two years ago and swear by it too after OCP’s for years. Keep up the great work @thelilynews!!!”

The Internet can be educational. It can also be anxiety-inducing and wildly inaccurate. Scouring websites for health info can fuel cyberchondria, the digital version of hypochondria. Here are two sites you can trust, according to a board certified family nurse practitioner: birth control site Bedsider.org and the Centers for Disease Control and Prevention.

What do “Gilmore Girls” and “Seinfeld” have in common? Both cultural touchstones feature scenes that hinge on birth control. In the former, Lorelai fears she might be pregnant after a night with her boyfriend, Luke, that got “primordial.” Despite the show’s focus on women, the episode is vague and skittish when it comes to the specifics of birth control. “Seinfeld,” however, takes the opposite approach. Elaine is forthright about her preferred contraceptive — the sponge — and when the product is pulled from shelves, limiting her supply, she’s unapologetic about gauging whether a guy’s “sponge-worthy.”
