My best answer would be to wait until your 6 week check-up w/ your OB/Gyne.
Your incision needs to heal and not have any germs introduced into the incision. That could cause it to break open.

Then wait until your 8w pp. You really need to have your incision checked on by your doctor before you can take a bath, sit in a whirl pool, enjoy normal 'married activities' etc.
