weight loss?

Brittany • Twin mom! My identical twin boys just turned 3 this June (2020) and our daughter is 1 1/2! Full time therapist and mom of 3 kids all 3 and under.
Since finding out I'm pregnant I have over hauled my diet to make sure it's a lot healthier.  I'm probably a good 30-40 lbs overweight currently with bmi of 31. However, since eating better I've lost almost 3 lbs in the last 2 1/2 weeks. I feel like I'm eating plenty and I absolutely don't starve myself. I plan on mentioning this to my doc at our first appt but wanted to see if anyone else experienced this and what they were told! Thanks!
