1 year old feels hot?

So my baby just turned 1 and feels pretty hot to the touch. She acts completely fine though and doesn’t seem as if anything is wrong with her. She does seem a little sleepier than normal though as she’s only been taking 1 nap a day now she’s back to taking 2 naps. I was assuming maybe it’s just her teething cause she still doesn’t have any teeth yet?? She doesn’t show any other signs of teething other than the fever though. I can’t find my thermometer anywhere so I have no idea what her temperature is. Should I call the doctor or just wait til I get a new thermometer either tomorrow or the next day. She’s felt hot for like 2-3 days now but like I said she still has an appetite and doesn’t act as if anything is wrong
