Uncomfortable to sleep!

11 weeks pregnant and since 8 weels it's been super uncomfortable to lay on any side :( my husband bought me2 huge fluffy pillows so I can lay a little elevated and he also told me to put a pillow in between my legs but I'm still in pain. It feels like a bad stomach ache anyway I sleep. I wake up at 4 am almost everyday and have to sit up so the stomach ache can stop. Any advice this is my second pregnancy
