What does it mean when ur belly has dropped??

Rice

Sorry if its a stupid question, but i dont know... Im ftm and im 32W4D .. What does it mean when ur belly drops?

Do you feel it drop?

Why does it drop?

And if it drops does it stay that way for the rest of the pregnancy...

Does it mean ull go in labor soon?

Thanks in advance for all the info ♥(*^﹏^*)
