I have gained sudden weight esp around my belly and thighs and  but diet is also not that much. I have hard facial hair growth especially on my jawline that looks bad. Although my periods are regular, but they last hardly for 2-3 days and little spotting later 4th day. I have started having bad mood swings and anger don't feel like talking to anybody. Since past one year I have changed as a person due to all this. I have thallasemia minor also ( anaemia) .I feel lack of energy and weakness also. Do I have PCOS or any hormonal imbalance? Should I consult a gynaecologist or any other doctor that can help me with this ...Please suggest and help! I will be grateful...
