Medical advise please

Ok, so i'm 12.5 weeks pregnant and all afternoon have been having pain in my kidney area. Normally I wouldn't worry as aches and pains are normal with a growing belly however I have had a lot of issues with my kidneys in the past and ALWAYS have microscopic blood in my urine tests. So with that, should I be concerned enough to call the dr in case of infection and it causing issues with the baby, or would you wait and see if it stops? Also, yes I KNOW none of you are doctors and if the pain gets severe I won't hesitate to get help but right now i'm on the fence looking for advice thanks!
