Kidney pain

Hi mommas❤️ I the last few days I have a tiny pain in my kidneys ... I was thinking is the baby but not so sure now as I am only 18 weeks. I think Its worst after I go to the toilet ( not another symptom, no fever, no pain during urinating etc)...in rest is more like an manageable ache, not dying of pain but just annoyed 😅😂

I will make an appointment but I am travelling and we are waiting to hit a bigger city .
