Opinions please???

I’ve read everyone say it’s like a sharp pain or a dull ache. But I feel like low grade cramps it happens only when I sit or lay down and then stand up. Or if I move a certain way to fast. It doesn’t usually last very long only about 15 sec. Sometimes it’s worse than others and I usually get it on the left side but sometimes it’s both. Does this sound like round ligament pain??? 10w 3d btw.
