Thanks for putting your query over here. First I would like to tell you it s very dangerous to take any drugs without physician s prescription.Misoclear drug is mainly used for inducing abortion and not for delayed periods. There can be variation in the cycle of periods.It is normal for such variation to occur.But if this irregularity becomes a usual thing,certain investigation need to be done like blood investigations,thyroid profile and USG.Causes of delayed periods can be pregnancy,anaemia,thyroid disorders,polycystic ovary syndrome and other genitourinary disorders. May I know what is your age?Are you married?Have you faced irregular menses before?any other complaints like heavy bleeding,pain in abdomen,general fatigue? Keep your weight such which is ideal for your height.have a healthy lifestyle,regular exercising and balanced diet (diet containing cereals,pulses,vegetables,fruits,nuts,dairy) Thanks and regards.
