18 months post-birth before I was pain-free BUT I put that long recovery down to the labour I had.

Basically you need to make sure you birth in a pelvis-friendly position and don't let the pushing stage go on for too long. Mine was worst case scenario - knees held back against shoulders, pushing for 2.5 hours, nothing happening followed by forceps.

So, be cautious. Don't fall for the platitudes that it will all go away after the birth. If you have a relatively 'easy' birth, chances are it will. But make sure you read up on what positions are good for you.
