When to worry about a fever?

✩M

Good morning mamas! My poor little pumpkin isn't feeling well. He was up and down crying quite often last night. He's 13 months and has a fever of around 102. He's tired and wants to cuddle, but has no other symptoms. His ears, throat, etc don't seem to be bothering him and aren't red. Eating and drinking okay. I've given him some ibuprofen, stripped him down to his diaper and we're cuddling on the couch, but I really don't know when I should worry or call his doctor? He's my first and since he's not showing any other symptoms, I don't know if I should be super concerned or not. I've heard mixed things about him possibly cutting teeth, but some say his fever is too high for that. I know when I have a fever I feel tired and lethargic, so I have to imagine he's like that too. So moms, what do you think? Should I be ready to run out the door to the doctor soon or is he probably ok? I have a tendency to get really worked up when my son doesn't feel well since he's my first child and I don't really know what I'm doing 😭
