Shooting pains in lower right side of back in early pregnancy??

Help! I’ve googled and can’t seem to find an answer. And I’m not sure this demands a call to the OB for “emergency services” (they are closed for the night). But ive been having lower back pain in the most recent days (no biggie. I assume normal pregnancy pains). But tonight it feels like a sharp/shooting pain down my lower right back.

I’m 7W2D and no cramping or bleeding. Should I be concerned? Has anybody else had this? I’m not sure if this is normal pregnancy pain or if I need to talk with my doctor.
