It has been a while since i was pregnant with my last baby but is it normal to not be able to sleep and to be hot all the time. I am only 10 weeks but i feel like i am burning up and my oh says thehouse is cold. Also i get up 3-4 times a night. Been having slight cramping in my lower belly but nothing ot worry about i don't guess since i havn't had and spotting. any suggestions.
