Hello,
Consecutive 3 negative
pregnancy test confirms that you are not pregnant. Beside pregnancy, reasons for late period are
hormonal imbalance, stress/anxiety, thyroid problem,
ovarian cyst, wt gain / extreme loss, irregular eating habits etc.
You will get withdrawal bleeding within 7-10 days of stop taking
duphaston medication. If you do not get your period, you need to undergo some relevant investigation after consultation with gynecologist. Take suggestive measures accordingly.
In the mean time, you must take balanced diet, avoid stress, drink plenty water/ fluid, keep bowel habit regular, do yoga/ light physical exercise, eat
carotene based vegetables and take sound sleep.
Be well & take care.
