Flynn didn't engage til labour, and I know this isn't what you want to hear right now (but someone's gotta say it so it might as well be me ) but if your EDD was the 4th and today is only the 6th then you have a little bit of time before you need to start "worrying" IYKWIM?

Some people I know swear by accupuncture to induce labour, bout only once bub is at least a week overdue.....

Not much help I know, but thinking of you
