sore,tired and fed up

I'm finding it so hard to sleep just now I'm 35+4 and I feel so uncomfortable, the bottom of my belly feels sore, my back is killing me, my heartburn has made an appearance along with a killer headache and sore teeth!, hate it loads because I just need to sleep!! The fact that it's also really clammy weather where I'm living doesn't help, please tell me labour is fast approaching especially feeling like there's a pressure on my downstairs area🙊
