Yes I do all that too. My husband says I'm sleeping too crazy cause i take all the pillows and all the bed 🤣

If you lay on your arms it could be why. Try using a pillow to hug at night to ease the weight and it should be more comfortable at night. I try to sleep on my side hugging a pillow and a pillow either between my legs or under my tummy to ease the extra weight I have gained during this pregnancy.
