ike everyone else here has said, my temp runs on what I always thought was the low side too. Abour 96 or 97. When I had my son I invested in a new, expensive thermometer, and the instructions provide ranges, and orally, it;s like 97-99.0 or something and under your arm, it's like 95.9-98.8, so after I saw that, I was no longer worried. They said those are "normal" readings.
That said, I didn't look at your info, so I don't know how old you are or if you have kids, but since I had my son (and I'm 34 now) for the last couple years i've been experiencing that same frustrating symptom. I feel feverish, (sometimes I even get the chills) but my temp is low. I finally figured out it coincides with my period. It's happening mostly right before my period. There are some other odd things going on too...and my OB mentioned Peri-menopause to me. Great. While it makes me feel far older that I am, when I get those weird body aches and chills, I feel better knowing it's just a PMS symptom.
Hopefully if you track it you can place it at a certain time in your cycle. (If you're a man, I'm SO sorry! --it no longer tells me on this screen;)
