what were your sign of kidney infection....?

Abby
What were the signs you had a kidney infection....? 
I’m 17 weeks today, for awhile now I’ve had headaches, abdomen pain, lower back pain, nausea loss of appetite etc. 
Had a blood test that confirmed a uti, but haven’t had the normal symptoms of one (stinging when peeing, need to pee etc) 
Instead I have a dull ache in my vagina that I can’t explain. Kind of like pulsing pressure. 
Anyone had anything like this....? 
I’ve also had a urine test today.
