Belly looking smaller!

I am 39 weeks Thursday. This morning I woke up and looked down and was like oh my goodness where has my massive bump gone! Black tights is last week 38 weeks, pink shorts is this morning (even after breakfast). Does this mean baby has dropped? Could labour be semi soon (🤞🏼) I never dropped with my first baby. I was at the hospital last night for a checkup and everything was normal and only 4/5 engaged written on my documents.

**no fluid loss overnight and baby’s movements have been the same. Im not stressed just curious if anyone else has had the same happen ☺️
