My first pregnancy I went off food a bit and couldn't eat a whole meal, this pregnancy I feel like I could eat everything. I'm 12 weeks 5 days today and feel a bit fragile like I haven't eaten, before evening meal I was feeling weak like I hadn't eaten and started shaking even though I had eaten lunch, even after eating a full plate of curry and a nan bread I still feel fragile in my belly like I haven't eaten, does anyone else get this?

Hope this makes sence
