This might be an odd question - but I very frequently feel cold and almost like having the chills (but not like having a fever chills). Some days it seems like I can never get warm, and I have been sleeping under a pile of extra blankets. I was wondering if this is my body still adjusting to being warm all the time when pregnant (DS is 12 weeks today), or related to breastfeeding and maybe I'm not eating enough to keep up with the demands on my body from creating milk. Anyone else experience this? Any ideas?
