Any ladies still losing weight in the second trimester?

An

I want to start by saying that I am overweight. I’ve been losing weight since the beginning of pregnancy. I’m almost 17 weeks and I’ve gone down 15lbs. I expected to start gaining in the second trimester but I’ve actually lost another 3 pounds. Has anyone else experienced this?

My last OB appointment at 14 weeks she wasn’t concerned because it was mainly due to eating healthier.
