So sick 😷

So I've been really sick lately (fever, headache, dizziness, fatigue, weakness) but even before that my nausea has been at an all time high! I'm in my second trimester so it should be going away but it's not and I've lost almost 15 lbs since my first doctors appointment! I brought it up at my last visit, they said as long as I'm drinking electrolytes I'm fine but I don't feel right losing this much weight. If anyone has any advice for what I can do to eat or anything please let me know!
