Surgery infection?? Please read 😬😂

Okay I’m 14 and got appendix surgery around 3 days ago,Everything seemed fine and of course it’s pretty painful haha.But I’m trying not to stress but my temperature has been getting really low and I’m coughing a lot,the doctor told me that a fever can be dangerous but did not mention anything about low temperature(I did some research,haha yep you guessed right.i googled it😪😂) It says that it may be a sign of infection.The surgery incisions are really tender and painful.Ive reordered my temperatures of the past 2 days and these are it(this morning it got as low as 95.4)

I only live with my dad and he isn’t up right now and gets mad when I over worry so I just need some help if this is a emergency or no😅

I may have also been walking around a lot and slept on my side a few times even though I wasn’t supposed too😬I know I was immature and stupid but yea I have no excuse
