Talk to Gynecologist on MENSTRUAL IRREGULARITY

my age at menarche was 12. I've never had a regular monthly menstrual cycle. i missed them often. about 3 years ago i took a homeopathic med. whenever i used to take that my periods would come and if i miss that month tou no periods stopped taking after few months. started exercise and ginger tea earlier this year. had regular periods for 2 or 3 months. after ramzan, i skipped periods for about 3 months. in August i got my periods. since then i get them every month not on same time also they are prolonged. i had slight but prolonged bleeding. but this time it was slight earlier but it's veen a wk i am having good menstrual flow (2-3 pads a day). last year a had an episode of severe menorrhagia. I don't know if it's oligomenorrhea or menorrhagia. and what are the causes. kindly help. what to do. i feel k home based remedies do work for me and i don't want hormone supplements but i am worried.
