Me and my girlfriend had sex last week on 6th sep. her periods were on 26th August. We used a condom and I ejaculated in the condom itself but there were spots near her vagina. For safety she took an unwanted 72 pill. She felt nausea or vomitting sensation right after taking the pill and later went fine. After 5 days I,e from this Friday, she started having vaginal bleeding whch is reddish brown. Its bleeding her heavily from last three days and we are worried. She also took a home pregancy test and found out to be negative. What are the causes for this vaginal bleeding whch is heavily flowing? How can it be treated? Until when will this continue ? Her periods are now expected on 25-26th of sep. Will they be on time? Is she pregnant?
