Left lower back/side pain at night

Jane

I’m 38+6 and this has started happening since Friday. At night, I’ll start to get a dull pain in the lower left back area, closer to my side than the spine. My first thought was kidney stones but the pain goes away in the morning. I’d say it’s a 5/10 on the pain scale, makes it difficult to sleep on their side, but because it’s not constant, I don’t want to feel silly going to the hospital. It’s pretty clear it’s not labour, I don’t have any of the signs yet, but this is also my first so I have nothing to compare to.

Anyone experienced something similar?
