Baby Dropping

Kelsey • Kelsey. Married. 20. Gave birth to my first child July 3, 2016
I'm a FTM due July 30th but my baby has been measuring several weeks ahead since about 24 weeks so I'm hopeful that she'll come mid July.. Can you ladies help me with some info about dropping? I know it's a sign that labor should be within the next 2-4 weeks but what was your experience as a FTM like? Pictures of before and after?
