HELP! I’m losing weight

Hi ladies so I’m 6 weeks pregnant and I am down 5lbs almost since finding out I’m pregnant. I have so many good aversions. EVERYTHING sounds disgusting and makes me queasy 😩 I’m literally crying because anyone who knows me KNOWS how much I love food!!! I can’t eat anything and I am so scared of something happening to the baby because I can’t eat. I haven’t thrown up but I’m extremely nauseous and have been for the past week at least. I tried to just eat bread and drink some ginger ale (also tried a flat coke as recommended by my dr) and omg I gagged so bad! I just spit it out last night and went to bed. My first pregnancy wasn’t like this at all, it was such a breeze. Please help me!!
