Back pain at 8.5 weeks

So aside from my morning workout, I’ve been pretty sedentary lately due to exhaustion and general feeling of laziness and just blah.

I have a desk job where I am sitting down most of the day. Yesterday I got up after sitting on a conference call for 2 hours and had a sharp pain and stiffness to my lower back that seemed to start around my hip and go to my butt cheek.

I stretched and it felt mostly ok except for 2 random episodes of what felt like a sharp zap in my hip/back/butt cheek as I was lying in bed trying to fall asleep.

Is this normal? Has anyone else experiences this?
