Does this mean labor may be near?

I am 36 weeks this week and have noticed it’s starting to look like my belly is dropping. On top of that, Ive noticed I’m having a much easier time breathing and a RAVENOUS appetite. When I was getting bigger I didn’t have much of one because my belly was pressing on my stomach but now it’s like I could eat a million things. I also have been slightly crampy but more in a “my period is coming soon” in of way.
