Losing weight first trimester?

I’ve lost 4.5 lbs since I found out I was pregnant. Im a normal weight and healthy BMI. I’m 9wks today and lost 1.6 lbs since a week and change ago.

I had the flu a couple weeks ago and wicked nausea that has improved with unisom/b6, but is still there. I have horrible aversions as well. Trying to eat a bunch of small meals and anything that sounds good at the time that I can stomach more than a few bites of. I just want to know I’m not alone with losing weight in the first trimester when I know you’re supposed to gain 2-4...
