Round ligament pain or something else?

I’m 10w 5d and Sometimes upon standing (maybe too quickly) I get these very sharp, intense pains in my pelvis. Almost cramp like but more sharp. I’ve doubled over a time or two. It usually goes away when I start moving again. Is this normal? Anyone else experience these type things?
