Weight loss during pregnancy.

Hey ladies...I am curious. Being overweight myself I am currently trying to lose weight and I have lost 10lbs since the beginning of Jan! Yay!! However I do have a question. We are TTC. Is it safe to lose weight during pregnancy since I am already overweight and by overweight I mean over barely 300lbs. I know women who have gotten pregnant at heavier than that however I do know that could prevent me from becoming pregnant. I am ovulating regular and AF is regular. Anyway thoughts on losing weight during pregnancy by eating healthy and not doing an extreme diet. Just healthy eating and drinking LOTS of water. Thanks in advance for the info! 😊
