Round ligament pain at night

I have been having trouble sleeping, restless legs, heartburn, baby kicks. But when I finally do fall asleep, I wake up with horrible round ligament pain, it’s sharp and painful, and it’s really hard to roll over in bed, or get out of bed.

I have the same pain during the day, while walking, and a pregnancy belt helps with that, but I don’t want to wear the belt at night because it is itchy and uncomfortable.

Anyone have any ideas to help the pain while sleeping?
