Round Ligament Pain?

Marissa • Pregnant #1 with endo

About 5 PM yesterday this super sharp pain started in my side (to the left of my belly button) and it hasn’t let up. Standing and walking hurts the most, like unbearable to walk. Laying down feels better but it’s faintly there. I’m 11 weeks today and have had no spotting. Does anyone know what this is or what I can do to help it?
