Talk to Gynecologist on Period Problems

I am un married with a height of 5'2 and weight 67 kgs I've been having problem with my periods although they were irregular since the first time I got them around at the age of 15, and was put on BC for almost a year after that my period did occurred every month but they never were on the same date, from May of 2020 things gotten worse again I skipped may, August of 2020 and gotten checked on September where my hormones were checked on day 5 and everything was normal except my ultrasound it suggested polycystic ovaries then this year I got 4 natural cycles and also gotten my hormones checked on day 3 of period in May 2021 and they were normal but still the problem is unresolved I sometimes skip them for a month or 2, or if I get them the flow is quiet lighter from what I used to have I don't want to be on medications what can I do now? Light period is getting me worried. Please help
