First trimester nausea

Dear mummies, I’m a first time mum in week 7 and experiencing stomach discomfort, I’m not sure if it’s acid reflux or nausea but it’s a full feeling that sometimes makes you feel hungry too. I do feel queasiness in my stomach for the most of the day. Worst of all, nausea strikes when I wake in middle of the night to pee, no vomiting and comes with hunger pangs. Did this happen to you too? Is this a combination of acid reflux + nausea? How to fight it? #pregnancy
