Losing weight while pregnant?

Maybe I’m over thinking this but is it normal to lose weight during pregnancy? I don’t have morning sickness, it’s not from that. I’m just eating WAY healthier than I ever have in my life lol. Lots of Whole Foods. I’ve lost 15 lbs in the last 7 weeks of this pregnancy. I’m 11 weeks now. I definitely had weight to lose and still do, my BMI is 30.
