When did you give birth to your first child compared to your due date?

I’m expecting my first baby and am curious what the most common time frame has been for moms to begin labor naturally with their first child. I’m 32 weeks and hate not knowing what to expect, but I’m hoping to let my body begin labor naturally. I would love to know when your body started labor compared to your due date and what your experience was knowing it was time to head to the hospital. I saw something today about someone being 42 weeks pregnant, although I know that’s rare and becomes risky. My husband, who was a big boy and the middle child, was born 18 days early. Both my older brother and I were born early. I’m curious if I will deliver early too even though it’s our first since our boy is measuring 89th percentile and because husband and I both were born early.
