The menstrual cycle is regulated by hormones and alcohol alters the metabolism
of different hormones. Hence heavy alcohol intake can lead to both early or delayed periods. In addition, stress
, both physical and mental, can also lead to early/delayed menses. Your drinking orgy would have stress out your body system, resulting in unexpected early menses. While this may not have lasting implications, you could have harmed yourself in other ways while so drunk. Hence please do not abuse your body further.
