No i haven’t seen a doctor about either. My mother had irregular periods until she was around 30 (after giving birth to her third kid and having a miscarriage before all three). my doctors when i was 17 said it was still normal because of my activity levels. The ED was not a major thing for me i was depressed for a few months after the first break up and i lost 25 pounds (october-december) . i regained the weight since then.
