PCOS?

Catherine
I have been reading up on pcos and i think ive freaked myself out. I have never had an irregular period. I was on BC for probably 8ish years, got off in august and have continued to have regular periods. I had a chemical pregnancy last month at 4 weeks and my period was only a week late. A little heavier but same 5 days cycle. Recently ive noticed an increase in dandruff and i believe some hair thinning at my temples. My husband says no but i see it. I was researching pcos and it says that these could be symptoms however the main one is irregular periods. Could my prenatal vitamins cause the other symptoms or am i just crazy? Ttc for 4 months with a chemical pregnany. Now in the fertile window so im really hoping its this month. Thanksss!
