Hello Thanks for your query. It is common to experience some kind of tiredness and fatigue particularly around a stressful event such as a marriage. However, if you have skipped your normal period, or have had an abnormal menstrual bleeding of late, then you should rule out pregnancy. Diet pills and attempts at losing weight too could make you feel tired, as could alterations in the thyroid hormone levels. please take a pregnancy test at the earliest , as there is no other way to rule out a pregnancy at home ! Take a test if you have missed a period. All the best.
