I hd sex wid my bf on 22nd December. My first day of periods was on 6th December. Wen he had withdrawn his parts frm vagina the condom still remain in my vagina. I had taken ipill within 30hours. Now its 28th December still i had not any bleeding or period. Can i take any medicine to prepone my period ? I am getting a white discharge now.Is there any chance of getting pregnant? Plz help...
