Saturday, I was exactly 5 weeks and the cold chills came out of nowhere. Then I got this ballon feeling in my chest. I have yet to feel warm yet. I have the heater on 80 and still shivering non-stop. when the cold chills happends the illness feeling is sooo bad. The nausea is so overwhelming. I'm only 5 weeks. none of my last pregnancies where like this. Does anyone have some advice or knowledge about how I feel. I'm going to call the doctor in the morning.
