Hi, Thanks for the query. Delay in periods can occur due to many causes, like hormonal imbalance, poly cystic ovary disease, thyroid abnormalities etc. As pregnancy test is negative after two weeks of missed period, there is less possibility for pregnancy. Increased vaginal discharge can be due to hormonal effect in the premenstrual phase. Possibly you may get periods soon, if you do not get periods in one week, consult gynecologist and get evaluated. If she recommends go for investigations like hemoglobin, thyroid profile, ultrasound etc. By this workup the possible cause for your problem can be identified. Then with your doctor s advice you can take tablets to induce withdrawal bleeding. Take care.
