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.
