Hi,
If you have not had a period for so long, then you need to see a gynecologist immediately. You need to exclude
pregnancy, no doubt, but you also need to exclude other causes like
hormonal imbalances,
polycystic ovaries, thyroid disorders, weight disturbances and so on. You may take a
blood test for pregnancy and also have a trans-vaginal sonogram. Consult your specialist for further care. Good luck.
