Chronic low body temperature

Hello everyone. I've had lyme (tests negative) for about 7 months now, along with suspected Babesios (had most symptoms). I was treated with doxy for 3 months and now most of my symptoms have dissapeared. I still have occasional night sweats and muscle twitching. Another symptom that I still have and have become concerned about is low body temperature. I never really thought about it until recently - but my temperature is always 96.9 - 97.8. It never gets to 98.6.
Should I be concerned about this? I've read that low body temerature can cause brain fog and lethargy which I have. I'm never really cold, but I constantly suffer with chronic fatigue. Is it the lyme or babesia?
