Hi,
At the onset of menarche (beginning of menstrual cycles) it is common for young girls to have slightly
irregular periods.
However, at age 15, such severe irregularity needs evaluation and testing.
Please seek an urgent appointment with a gynecologist, who may like to examine you, get the baseline blood
tests done, and also get specific investigations (hormonal profile, urine culture, ultrasound abdomen and
pelvis etc) done.
What is your weight? (Young overweight hirsuit women with menstrual irregularities occasionally have a
condition called PCOD.)
All the very best to you!
