Should I been concerned

So I’m at the beginning of my third trimester and when I got up this morning to go to work I went to stretch and I couldn’t stretch all the way because when I tried it got a sharp pain in my lower stomach kinda by my waist not like a lightening sensation but just straight pain as if someone just stabbed me. That was at 9:15 this morning and it’s now almost 2pm and that pain still hasn’t completely went away no matter how a stand or sit and move I have a sharp pain there.
