Dropping!! When is normal to drop

Over the past 5 days everyone is commenting on how huge I got over night and that I dropped ... I’ve definitely not felt much movement lately as he’s pretty much out of room .. I’m only 33 weeks but I have a feeling I won’t last much longer ... any advice or tips I’m a first time mom and pretty young I was only 85 pounds before pregnancy and I’m over 125 now ... I’m due December 18th The back pain over the past week is getting increasingly worse and I feel like I’m completely out of room for him to keep growing much longer and just wondering if I have dropped already does that mean I’ll have him sooner any advice comment or help is greatly appreciated
