Usually my periods will start between 30 to 40 days every month. i had my periods on may 2 and took beta hcg test and urine test at day 45.both were negative. so consulted doctor and dr suggested me meprate 10mg for 4 days(june 23 to june 26 - 10 tablets).i have pcod as well. dr told me that periods will get started within 7 days after tablet course and dr confirmed that it wont induce period if im pregnant.its almost 13 days since i had my last meprate tablet. but still no period.
