Concerning or Normal?

So this morning I woke up and my right hip was achy. Well after a few hours that went away. And since then I’ve been having stabbing sharp pains in my left lower back. Kind of opposite of my hip bone. I can be walking, sitting or laying down and the pain will go from achy to extremely sharp for no reason. Multiple times an hour. Is this normal? Or should I call my on call doctor? I’m 21 weeks pregnant and a ftm. So all this is new to me
