Help! I hate eating!

Other than struggling to drink water, I'm 9 weeks and 3 days, I have no interest in food whatsoever. I know I need to eat so I try fruit or salty crackers here and there, but it's been 3 whole days with out an actual whole meal. As soon as I attempt anything else the headache and nausea come in. 😣 I'm active duty and trust me when I tell you, the Coreman are in no rush for advice until my next appointment UNLESS I'm dying..in which case I'd call 911. Any advice?
