Losing weight in first trimester?

Never thought I would complain about losing weight. I already called the doctor and left a message but they haven't gotten back to me yet. I feel like I'm being very paranoid. I was overweight when I got pregnant, BMI of 29.5. Now I'm only 10 weeks pregnant and I've lost 8.5 lbs since getting pregnant. I'm really not trying to lose weight, and up until now weight loss has been an EXTREME struggle for me with my insulin resistant PCOS. I'm getting really worried that I should not be losing weight at this point, expecially so much. Has anyone had this happen? I haven't had any vomiting but I've had aversions to meat. I feel like I've still been eating enough though.
