Baby not dropping

Miranda • Engaged on 6.12.18💍 baby girl due July 8th 2019 👶🤰

Has anyone had a successful vaginal delivery where there baby hadn't dropped until labor actually started?

I'm 38w 3d and baby hasn't dropped. Baby is an average size and I am 1cm, 50% effaced. My OB didn't mention being concerned but I also never asked. I'm being induced Monday due to Gestational Diabetes. My mother in-law said to prepare for a C-section because baby still might not drop when I'm in labor. That was her experience with my fiance. He never dropped and she was in labor for over 24hrs.
