Losing weight

So I am overweight by a lot. It's something I've been struggling with for a long time. Since finding out I was pregnant I have lost ten pounds. I'm not vomiting. Do have occasional nausea. I feel like I'm always eating but making smarter choices with food. Is it safe to keep losing weight like this? I'm 8 weeks today so I know I'm not supposed to put on much if any weight and they encourage not gaining much if already overweight. I'm excited to lose a little but I want my baby to be healthy
