34w5d belly dropped

I'm 34w5d, and I've had people point out that my belly has dropped. This is my first pregnancy. Should I be worried about an early appearance or is this a normal time for this to happen? Also Braxton hicks have becom an everyday thing lasting 20min-1hr in infrequent bursts and then just going away, sometimes 1-2 times a day. Am I just worrying or could she come early?
