I believe I did not cum Inside her but since she was not sure so she took ipill (ecp) after 6 hours of intercourse. After four days i.e. On 1st aug at 1: 30 am, she started bleeding and she said that the pain and blood was just like her periods. We both are very tensed as we don't want any pregnancy. please help. We will be grateful to you.
