I have never consulted a gynaecologist before and so I'm posting my doubts here. I've been having sudden, late, irregular periods for the past 3 months. Before that, my cycle has been regular every time. Haven't got pregnant in 2 and a half years of continuous unprotected intercourse. Have excess hair on my back and lower back compared to the rest of my body but it's been like that all my life so I've always thought it to be a result of my Punjabi genes. Being 5'4 and 21y/o, I've gained 10kgs in the past 18 months starting from 50, to now 60kgs. And lastly, I have always had very oily skin but not acne. Does this mean there are high chances of me having PCOS and never being able to conceive in the future? Is PCOS/PCOD treatable depending upon my young age?
