Hello Doctor, I am 21 years old. My last proper period was from 13th to 17th August 2026. Since then, I haven't had a proper menstrual period. My previous period dates were: - May 18–22 - , June 8–12 - , july 5–9 - , August 13–17 . In September, I experienced pink spotting  but my actual period never started. The same thing happened again around October 1. I stopped taking emergency contraceptive pills in March 2026. I had previously taken Divery when my periods were delayed that was in the month of March . I don't have noticeable symptoms like weight gain, acne, excessive facial hair or abdominal pain. I would like to understand why my periods are delayed, whether this could be due to hormonal imbalance?
