It could be round ligament pain....I don't have it sleeping but it happens to me if I go from sitting to standing too quickly. I don't remember it with my first but I have it this time with my second
When you get up in the morning do you get up normally. Most of the times I have to get up slowly cuz of the pain
Yes me if I lie on my left side I get a pain or cramp feeling but if I sleep on my right side I dont get a pain at all
