Abnormal Period Problem

Hi I'm having abnormal symptoms with my period, I feel like all symptoms way be related to hormonal issues: depressed (extrmely abnormal for me I'm a happy person and have never dealt with this EVER), anxiety, ance, bloating, wierd cravings, constipation, some periods lasting longer then others, and the one symptom that bothers me the most.... facial hair is growing in places i've never had to deal with before. Would going on the pill help with all of this? Or is this a more serious matter that needs special medical attention?
