Aww mama, that sounds really tough! Seven weeks pa lang kaya expected talaga ang hyperemesis, pero if you're vomiting everything you eat within 30 mins to an hour consistently, I'd really suggest checking in with your OB kasi it's important na kumain ka and stay hydrated para sa baby, a few of us had similar experiences and when we told our doctors, they gave us options like anti-nausea meds or smaller, more frequent meals na tumutulong talaga. Kapit lang, first trimester is the hardest part ng iba!
