Most of my pain was gone as soon as my last babies were born, but I do still get pain 3.5 years later and at times have been so bad I've had to go back on crutches. All I can suggest is keep icing when you get sore, and see a chiro or physio as soon as you possibly can. The removal of the weight from your pelvic floor should make things easier, but if you had a difficult birth it can exasperate the injury (especially if your legs were pulled apart for pushing) so it's not unusual to still be in some pain post birth.
