Two women were hospitalized after using a vacuum to make their menstrual periods end sooner, according to new reports.

A Seattle nurse claimed the desperate women, ages 19 and 23, went into shock this week after attempting a dangerous, decades-old technique known as a menstrual extraction, the Mirror reported.

“Ladies… Please stop using your vacuum hose to end your period early,” the nurse tweeted, before switching her account to private. “You’re gonna wind up sucking out a lot more than blood! There were 2 cases of this so far this week and both women had to be admitted. Just… STOP!”

“I don’t know if it was Eureka, Dyson, Hoover or some Walmart brand, but yes an actual vacuum cleaner,” she added.

She followed up with a tweet about the dangers of using a vacuum to suck out blood, according to the Mirror.

“Your period has a steady flow of its own that for all intents and purposes your body can tolerate,” she wrote. “A vacuum increases the flow over 1,000 times which your body can’t tolerate, therefore sending you into shock.”

Menstrual extractions, which involve the use of a syringe, cannula and tubing, were common before abortion became legal with Roe v. Wade decision in 1973.
