Popping sensation during sudden movements

Has anyone else experienced a popping or snapping sensation when making a sudden movement? Like just sitting up from the couch, or turning your torso too quickly...I’m around 21 weeks pregnant with my second baby. It’s not painful, but kind of shocking...like a supppper hard kick, but there’s no way my baby can kick that hard yet! I never felt this with my first.

Calling my dr tomorrow ASAP but of course this would happen Sunday night so I wanted to see if I could get some answers on here too!
