How "overdue" were you when you had your HBAC?

Just out of curiosity, how long did you wait and still feeling comfortable to have a HBAC?

My due date is tomorrow. I'm not in any way feeling anxious (yet??) I'm just wondering because with my first I went into labour spontaneously on 39+1 (and had the baby via c/s).

My midwife & I had a quick discussion about it earlier in pregnancy and that unfortunately if I go pass 42 weeks we'll have to go to have hospital birth, and I assumed will have some sort of intervention to start labour. I'll meet her tomorrow so will discuss further.

Who knows I might go into labour tonight! :)

Note: My due date is based on LMP, I never confirmed it with growth scan.

There is a post on here somewhere with info from a report with stats on still births at certain gestations. It is worth bearing in mind if you go post dates.
Not much help on hbac though, sorry.
