When did you go into labor with your 3rd baby?

I am currently 36+5 and just curious if 3rd babies tend to come earlier than previous pregnancies. My first came spontaneously at 41 weeks, second spontaneously at 38+5. With baby 3 I was dilated to a 3 and 60% effaced and baby was already engaged at my 36 week checkup. I know this doesn’t mean much for labor, but I have also been having prodromal labor daily since 35 weeks. I am just wondering if this baby may come soon or if this all normal for a 3rd pregnancy. I would love for him to come on his own before my induction date at 39 weeks since I am going for a VBAC. Any insight would be great 🙃
