2 month shots

My daughter just got her 2 month shots today but she got them a little late she will be 3 months on the 19th. But she got them about 3:15 this after noon and did really good with them didn’t really cry until the third one but only cried for a second then was fine. But it’s now 4 in the morning and she woke up about 3:30 and was in her bassinet with a blanket and it’s kind of hot in my room but I felt she was a little hot while I was feeding her so I took her temp and it was 99.9 then 99.7 and then I put her in her swing in just a long sleeve onesie no pants or a blanket just to maybe to let her cool off for a little and it went down a little to 99.4 so it’s going down so that’s good. But I was just wondering what her temp would be for me to have to take her in to the hospital. She’s not crying or fussy just a little whiney but it could be cause she was tired. I know this is a lot but I’m a ftm so I’m still kind of new at this and don’t want anything to happen to my little girl. I know they tend to get fevers with their shots but her doctor didn’t explain anything just said her weight and everything was fine with her physically gave her her shots and said when you’re ready you can get her dressed and leave. Any advice?

UPDATE:

It’s down to 98.7 now so maybe she just needed to cool off a bit and she’s back asleep
