Heads up, anyone who’s currently taking birth control! A popular form of oral contraceptives has just been recalled because of a packaging mistake that could result in pregnancies despite being on the pill. Here’s what you need to know.

Mibelas 24 Fe, a chewable birth control pill, has been voluntarily recalled after it was discovered that placebo pills had been placed in the wrong spots. Though all needed pills are included, the fact that they’re in the wrong order could result in an unexpected pregnancy.

If you’re taking Mibelas 24 Fe and concerned about the recall, you can compare various months to see if any pills seem to be out of order. According to Vice, in the problematic packages, “the four, darker placebo tablets [are] at the beginning of the 28-day cycle, instead of at the end after the 24 white pills.”

Another way to tell if your pills have been affected is to locate the lot numbers. You’ll want to watch out for lot No. L600518, with expiration date 5/31/2018. If you’re not able to find the lot numbers, that’s also improper packaging, so beware.

Additionally, the National Drug Codes for the improperly packaged pills are 68180-911-11 for the wallet of 28 tablets and 68180-911-13 for a carton of three wallets.

If you’re still unsure about your birth control, it’s always better to be safe than sorry, so be sure to check in with your doctor.
