Between 38-39 weeks. I carried so low I never noticed but my fundal height didn't change and mw commented dd had probably engaged. I have read for STM+ that it's not uncommon to not engage until labor.
I had a cervical check for shits and giggles at 35 weeks and 5 days and baby was very low and engaged already. Which explains why so many people were talking about how much room I had under my boobs already.
