It's completely normal. Drink plenty of water and just make yourself comfortable lalo na pag gabi. Elevate your head. Don't sleep with your back. Sleep on your left side.
Early weeks of pregnancy ganun talaga mostly. If wala gana kumain try kumain pakunti kunti lang para di rin ma upset tummy mo. Yung mapait na panlasa pregnancy hormones lang talaga yan so let's pray mawawala din sya pag 2nd trimester mo na. Try mo uminom ng citrus juices and eat sour foods... it helped me before.
Also, it's better to ask your OB for advice. ♡
