Confused pls help

Regular po ang mens ko. 28days cycle. Then last year mga october november 2023 nag iba po. Minsan maaga, minsan 30 to 32days. Ngayong january 2024 nagspotting ako january 18 ng gabi, then january 19 lumakas onti tapos january 20 halos spotting na lang, january 21 nagstop na sya totally tapos january 22 at 23 spotting nanaman medyo brownish color. Sobrang naguguluhan na po ako tapos masakit ang boobs ko, bilis ko mapagod, laging antok at nasusuka/naduduwal kapag may naaamoy na kung ano. Pls help me po. May naka experience na din po ba ng ganyo. Thankyou in advance.
