i am nearly 27. i took i pill within 12 hours of unprotected sex. following which my period came about a week early and it was lighter than usual.(may 25 to 29). following that there has been no appearance of another period till today, except for some spotting (which i have never had before), from june 17-24, when i did heavy physical activity. i understand that i pill may cause temporary disruption in menstruation. but is my condition normal?
