Losing weight?

Mandy • Mommy of 2 wonderful boys 5.18.17 💙 4.3.19 🌈💙

I'm 16 weeks and 4 days went to the doctor today and I have lost weight. He asked to see me back in two weeks unstead of four is it because of my weight loss? I have had no morning sickness. Has anyone else lost weight during the 2nd trimester?
