Cramping 😩

Does anyone else have cramping some days? It's normally low one sided cramps and they happen even when I'm just sitting down so I'm not sure if they are round ligament pain or not, but they sure make me nervous. I'm 23 weeks tomorrow and have had them off and on for a week or so. They're really stabby feeling and on one side or the other, right above my pubic bone. Does anyone know what this could be? I'm trying to not let my anxiety take over.
