Severe Round ligament pain

Jennifer
I've had a severe pain in my lower tummy all day (about 12 hours) I'm 13 weeks today and presuming it's round ligament pain but wanted to know if any of you ladies have experienced it for this long. It gets worse with sudden movements but is there even if I'm just standing or sitting in the wrong positon. 
Please let me know if any of you have experienced this.
