8months of pregnancy.

You can try drinking hot liquids or eat food while it's still hot, boiled dhaniya water with real ghee can also help loosen up the stomach, it mainly happens when ur baby is not moving much so drink g hot liquids like hot milk or soup can make ur baby move and loosen up the tummy......good luck new mommy😘

Previously I have the same situation as you and I consulted the doctor. The only answer I was given from him was “nothing can be done. It can only get well after delivery” I was like “What?!”
