LOL I had hiccups "in my butt" the other night. I tried to explain it to DH and he just looked at me weird.
With my last pregnancy I had tickling on my cervix from the inside out for a few weeks. A VERY weird sensation and impossible to describe to someone who's never been pregnant. Apparently, ds had his hand up above his head and kept wiggling his little fingers. Yet, I still went two weeks overdue with him!!
Baby can even "drop" while you're in labor. It's good if baby has already dropped but not really a sign of impending labor.
