Stomach ache/pain at night

Leah
Hi, i am 38 weeks + 2 days and in the middle of the night for the last week i wake up with stomach ache. It's not period pains so i don't think it's contractions it just aches so much. I am in so much pain when i try and move but usually when i move to the other side it eases. Is this normal and happening to everyone? When i wake in the morning, my stomach aches so bad but usually eases once i start walking around.
