Talk to Gynecologist on Hormonal Imbalance

Im 18 years old. After aug 2024 after my periods ended the brown spotting would go on for many days so each menstruation cycle goes for 7,8 days with just spotting on last 2,3 days and I used to have barely any period pain but in Dec 2024 i had unbearable pain and cramps but after that my cycle got regular on its own and no unbearable pain but my father died and i think due to the stress my periods this month were 6 days late. I think all of this is related to hormonal imbalance. My facial hair growth has started alot and im facing hairloss too. Is seed cycling a good option to deal with these issues??Which doctor should i consult for this?
