Week 39, and baby is still making huge movements!?!?

Nicole • I'm 29 years old, married to my hubby since 2012, together since 2009. Pregnant w/ our rainbow baby due 9/2015!
Question. I'm 39 weeks and 2 days pregnant. My OB did a cervix check 2 days ago, and ever since, the kid has been going crazy in there at night. Not just nudges or punch/kicks like the last 3 weeks, but big pushes and feels like roll attempts! (Which I was told there wasn't space for anymore, and they don't feel nice now that his is so big!!) He has been head down/cephalic for weeks now, so I'm hoping he didn't just breech himself tonight with the big rolls I felt (I should be able to tell in the morning when he gets his hiccups) but has anyone else noticed bigger not smaller movements towards to last week(s)??
