Hi Sir, Me and my gf had sex on 16th June. After 25 hours she took unwanted - 72. Her period was expected to be on 2-3 July. She started bleeding on 3rd of July night. But she said it was lighter than usual period bleeding, she was also having symptoms like pain in abdominal from 30th June. Her bleeding stopped on 6th July morning. Her period usually is of 2-3 days. Now my question is that are we safe from pregnancy? Was this really a period or I have read somewhere called implantation Bleeding?
