I had to use the Fahrenheit to Celsius calculator but in the U.S. we consider 37 Celsius to be the normal. Everyone varies a little but chronic low grade fever is a concern that you should get checked out.
"Low-grade fevers can occasionally accompany serious medical conditions. Seek immediate medical care for serious symptoms, such as irritability or inconsolability in children, confusion, decreased levels of consciousness, difficulty breathing, difficulty walking, severe pain, neck rigidity, seizure, blue coloration of the lips or nails, or rapid heart rate.
If your low-grade fever is persistent or causes you concern, if you have other symptoms of infection, a weakened immune system, or have chronic medical problems, seek prompt medical care."

It's always better to be safe than sorry. I hope this resolves soon.
