Hello dear Understand your concern If you got slight bleeding on first day then do not worry. Some time delayed period and slight bleeding is normal and it does not require the medicine. If period will be delayed by 7-10 days then you have to find the cause of delayed period. Treatment will depend on the cause like hormonal imbalance, ovarian cyst, change in life style and eating habit, excessive stress and thyroid dysfunction. Above cause should be rule out by consulting the gynecologist and after proper investigations. Generally period will be induced by progesterone injection or tablet under the advice of gynecologist. Avoid stress, take healthy diet, fresh fruits and green leafy vegetables, drink plenty of water, do regular exercise like walking and yoga.
