I don't know if that would be your period now or not. Bleeding for 5 weeks is a long time, and then starting up again, so soon. Have you done anything extra strenuous?
I only bled for 3 weeks, and got my first period when he was 11-12 weeks old.
I would go to your doctor, or call a health nurse.
As far as the pain. I delivered naturally, but tore backwards, towards my problem.
Did you tear frontwards? That could be it
