question: Hello. My Girlfriend friend and I had unprotected sex a week back, and on that day she was on her 2nd day of Periods. Immediately within 24hrs she took a Contraceptive Pill as we don t want pregnancy at any cost. Now, after 3-4 days since the intercourse happened, she is witnessing slight bleeding. The bleeding is unusual, it came on alternate days. Could she be pregnant? We don t want pregnancy, please help!
