With my 1st she turned and dropped, engaged, at 7 months. Thought she was going to drop out on the spot. I walked around 5cm dilated for weeks and not even a BH to encourage me. I had 1 hour of contractions then they stopped due to bad news. I ended up being induced as I was dilating but no pain. I had a 2 hour labour from the time they broke my waters.
All the best as you wait for the birth of your son
