Hello madam, well from the history you have given, as your doctor said it could be a transition from pre menopausal to menopause
and also because you are 45 now. ..most women experience hot flushes, mood swings like irritability, lethargic..Some lack concentration....women experience delayed and irregular periods
.....These are due to hormonal
changes occurring in the body......But if you experience discharge from your vagina associated with smell or itching, then you may have to consult your gynaecologist to rule out any underlying infection...hope i was helpful to you. ....
