Welcome to HCM.
Missing periods for three consecutive cycles in a woman who was previously menstruating is called amenorrhea
. There are many reasons for this. Most common is hormonal
imbalance, prolonged illness, and increased stress
. In your case I am suspecting hormonal imbalance as the cause.
I suggest a detailed examination by a gynecologist to rule out causes. I also suggest testing of Thyroid
If hormonal levels are imbalanced it can be very easily treated.
