Losing weight in 2nd trimester??

Emmily
I'm 15 weeks and 4 days today. And I have lost like 5 pounds over the past 2 weeks. I have had no morning sickness and I eat like a grown man... Is anyone else having this issue or any ideas as to what it could be? I contacted my doctors office but the nurses take forever to get back to me and I'm worried. From what I read online it just jumps straight to bad bad and more bad... 😞 anyone have any ideas?
