Maybe: Planb is not 100% effective, but it is likely >95% effective at preventing pregnancy, so you need to check a pregnancy test. Breakthrough bleeding after using planb is common and is not your period. It also works to delay ovulation, so your next period might also be delayed. And yes, it could be associated with bloating.
