Weight loss while pregnant

Have any of you ladies tried losing weight while pregnant. I’m extremely overweight. I don’t think people can actually tell how much i weigh. My muscle mass keeps me from looking as fluffy. 4’11 192lbs size 12/14 at 26w. 170lbs prebaby. My BMI puts me at a higher risk. I don’t want to put my baby in danger. We still have 14 weeks to go. Have you tried losing weight during your pregnancy or have tips on how to safely?
