HELP!!

I was 9 days late today and I was so sick with chills so I took 3 test and all are positive! I'm super excited for baby #2 but I'm concerned about the chills they've been non stop and it's 80 degrees outside and I'm still freezing. I googled it and it says it can be a sign of kidney infection so I've freaked myself out. 
Anyone had chills in early pregnancy?!
