Did she drop?

I'm only 31+2 so it seems way too early!

But Friday my dad told me that I had dropped and I realized that I have been feeling movement in my pelvis when before I had only ever felt her on the sides (she was laying transverse) or near my ribs. But now I have felt hiccups in my pelvis, have been having back pain regularly, can feel her wiggling around realllllly low, can eat more and my stomach is on my lap when I'm sitting and the bottom of my bump is a lot more sensitive than it was before.

It could all be a coincidence, or maybe she has just gotten bigger or flipped over and I can't tell the difference. I'm also 4'10 so maybe she is just out of room! I have no clue!

I'm not really too nervous about preterm labor, but I'm just wondering what you all think! Thanks! :)
