I had my last period on 15th November and took unwanted 72 on 23rd November (1.5 hours after the intercourse). I had brown vaginal discharge on 29th November which lasted for about 2-4 days (withdrawal bleeding) . I took a urine
pregnancy test on 29th of December and on January 5th... Both of them are negative. I have not got my period yet. What should I do? What is the reason and how long will it take for my period to be regular?
