Active baby and back pain

So my baby has been active this entire pregnancy. I felt him at 12 weeks (this is my second pregnancy so I know it wasn’t gas). So this morning, I woke up to pee and had some intense lower back pain and he started going crazy. Kicking and tumbling like he always does, but a little more? If that makes sense. It also sometimes is sore when he pushes out or kicks me. Should I be concerned or only if this back pain persists? My next appointment isn’t until next Tuesday, July 7th.
