Weight loss!

So due to morning sickness I have barely been able to keep anything down. I'm 10 weeks +4 at the moment and I just figured out that I have lost 35.5 lbs since falling pregnant, this seems like a lot to me! I was overweight but I'm considered a healthy weight now. I didn't notice until today because it really doesn't look like I've lost weight, my stomach is so bloated. Do you think this is anything I should be worrying about?
