Baby dropping?

Miranda
So my first daughter never dropped until it was time to push. I'm currently due with my second in the 30th and I'm pretty sure she did...
Stood up to with a sudden need to pee and the second I did there was a very sharp pain in my cervix that made me drop in my tracks. 
I heard that with baby dropping it makes it easier to breathe and heartburn is better. Her movements feel lower than normal and it does feel a bit easier to breathe. My heartburn when I lay down is typically disgusting and I have to prop myself up to nearly sprung up straight and take the Tums. Tonight it's tolerable.
Has she dropped?
