Questin and ranting?

So, I'm 30 weeks and for the past week I just can not sleep, if and when I finally do fall asleep its not not fully asleep, then every single morning I wake up at 4 am and 6am, I feel like I had 2 hours of sleep in a week, I'm walking around like a zombie, i get bouts of energy to clean but other wise have no energy. Also for two days now I have had to poop 3or 4 times a day, sorry tmi, I have tried everything in my power to sleep and can't, not to mention I can't eat? Everything makes me sick no matter what it is, I was checked last Wednesday and was on 25% effaced no dilation but what is going on with me?
