can you get pregnant if you had unprotected sex one day after using plan b?
Yes, it’s possible to get pregnant. The morning-after pill (AKA Plan B or emergency contraception) can help prevent pregnancy when you take it after having unprotected sex. But, it won’t prevent pregnancy for any sex you may have after taking it. So if you use the morning-after pill and then have unprotected sex, you’ll need to take it again.
If you’re having vaginal sex and you don’t want to get pregnant, use an ongoing form of birth control like the pill, patch, ring, shot, implant, or IUD. Using both a condom and another method of birth control can make sex even safer from both pregnancy and STDs.
