My boyfriends condom broke last time we had sex and i took plan b right after because im really scared and i don't know what to do now please help ?

Nothing more to do: Assuming you took the Plan B as directed and appropriately, there is nothing more that needs to be done from a pregnancy prevention standpoint. Need to wait until your next period. However, you should also be aware of possible std symptoms of discharge, pain, fever, etc. As a broken condom can allow for std transmission. See your doctor if you notice these symptoms, or do not get your period.
