Mam I went there after 7 days of my missed period then the doctor tests it was negative. And I want to tell you one thing that is I took I pill within 24 hours of sex. And that doctor was saying the period are getting late because of hormonal imbalance which is caused by the pill. But I want to know that for how much time it can be delayed or there is any medicine? फिर withdrawal bleeding so please recommend me.
