Weight loss in pregnancy?

Chelsea💜 • Baby number One & Super excited!! September 23rd!!!
So yesterday was my second appointment and I lost 5lbs in 4 weeks. Not nauseous or anything. Just more of a food aversion from everything. Especially meat. I only eat when I get hungry maybe twice a day but I just don't feel hungry, and I snack healthy with peanuts or cucumber but I guess that's not enough. Lol What can I eat to make sure I get enough nutrition and try to have a balanced diet that's NOT meat. It's crazy because I'm not even a vegetarian.
