Metallic taste and upset stomach 24/7

Bella✨ • 23. Mother of one 💙🏀
Today I am 14 weeks and 2 days for the past 4 days I have been getting a metallic almost tuna taste in my mouth . I don't know how to really explain it . Also every morning when I wake up my stomach is in pain like a bad stomach ache . It will stay that way all day everyday only going always for a few mins . I know it's not ligament pain bc I've felt those and know the difference . It's more so like someone has punched me in the stomach and now i am internally hurt . I bought a preggo pillow to see if it helped but it hasn't helped at all . Oh yea and I'm so thirsty . I go through almost 7 bottles of water by 5pm everyday and I am still very thirsty . I literally feel my throat dry up . Sorry for the long post but I was wondering if any other moms feel this way or if you think something's wrong . My next Drs visit isn't until next Saturday.
