Hello,
In the current scenario, the best thing to do is to see a gynecologist, undergo a complete physical evaluation, get a serum beta-
hCG titre estimation along with a trans-vaginal sonogram. This will rule out any
pregnancy or if present, confirm the
gestational age and the viability, so that you can take further precautions. If pregnancy is excluded, you should get further investigations including a complete
hormonal profile to know the cause of the absence of cycles and for further management. Hope this helps.
