just wondering if you can actively try to loose weight while pregnant? i have lost about 15 kilos in the last year and i still have 7-10 to go. however now that i have lost a bit of weight i sorta want to start trying for another baby soon but still loose some weight as well. is it possible/ safe to excercise (like a step class at gym) and not so much diet but not eat as much while pregnant? or should i just wait until i am at my goal weight before trying?
