Its really a concern that she is not getting her periods since 1 yr. You shoud check with besic tests like  fsh,lh,thyroid, sr prolactin.  Ultrasound pelvis.  Are there any children?is this happens after any surgery? Any intrauterine devices  like mirena introduced? Is she taking any medicine?   All can be answered by gynaecologist. Meet gynaecologist.

Hi there...I can understand your concern. What has been doing till now? Why hasn't she got it checked still? Irregular menstrual cycles can be due to many reasons like anaemia, thyroid disorders, pcod, fibromas, stress, drug intake. She will need detailed clinical examination and further investigations including ultrasound abdomen and pelvis, hormonal profile. So kindly consult a gynaecologist for further evaluation.

Hello there. I can understand your concern.  Was she getting her periods properly before that? Does she have any issues with thyroid? Is she overweight? You need to take her to consult a gynaecologist in person for further evaluation and management.  Some tests need to be done like ultrasound abdomen and pelvis, thyroid profile and others will be suggested by the gynaecologist after she examines her.
