Wake from stop mode

Hi,

     I am using a STM32LO72 device and entering stop mode using

     HAL_PRW_EnterSTOPMode ( PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);

     I have configured the RTC AlarmB to wake the device but it wakes almost inmmediately.

     Would anyone have advice on how to tell which interrupt has caused the exit from STOP mode?

Thank You 

Regards
