As such there can be a variety of causes of missed period like hormonal imbalance, weight gain, weight loss,PCOD,thyroid dysfunction, pregnancy to name a few . If you are sexually active and have missed your period pregnancy should be ruled out .Ideal time to test for pregnancy by a home pregnancy test is 1 week after missed period and morning urine sample should be used . Other possible causes include hormonal imbalance .
Well you should consult your obs/gyn doctor and your doctor may advise some form of progesterone to induce period and further investigations like ultrasound ,blood work like Thyroid function test, LH ,FSH etc may be advised for further diagnosis and management .
