29 weeks sharp pain

About 2 days ago I was standing up and had a really sharp paint surge through my pelvis and lower abdomen. It was to the point where I couldn’t move and needed help getting the rest of the way up. It went away after I stood up and walked around for a little while. Is this something I should be worried about? I’ve never experienced anything like that (I’m a first time mom). I know no one is a doctor I looked up what it could possibly be and google said it’s normal but has anyone else had this happen?
