When your pregnant you don't bleed at all until you have the baby!!!
If it goes on for very long you should see your GYN to get some help with the problem.

About one to one and a half hours. Not long at all
You have to decide by having sex with her. If blood comes out the person who didn't bleed, takes the child.
