OK so three nights ago I was sleeping and it was freezing in the house. I was covered in one thick blanket and I woke up and was sweating like crazy and my body was on fire and I was just so hot. It happened the next night too then the night after that I woke up freezing I was shaking uncontrollably and I had to cuddle my fiance. It hasn't happened again but scared it will. Also I have been having indigestion like crazy and my nipples have been purple and hurting like crazy for about 2 weeks now. My friend told me see had this symptoms when she found out she was pregnant and then my sister in law told me the cold and hot at night thing could be because of a kidney loss. I need other opinions help my please.
