Anybody else lose weight during their pregnancy? It's kind of concerning me...

The left picture is 10 weeks, the middle is 11 weeks and the far right is 12 weeks. Still not showing but I can feel little flutters now (pretty sure that's what I'm feeling haha)!! :)
You can't tell in the pictures but I certainly can tell with it being my own body that I have lost weight. Is it normal to lose weight in the first trimester? I've lost 8 pounds almost :( but I'm not sure why. If anything I eat more now but it's been concerning me a little bit. I'm hoping the baby is okay :/ I have an appointment in two days to check up on our little one :)
