TTC but not happy with weight

Kass
So since March been TTC and since then trying to lose weight as well. I was doing good then just lately gained everything I lost. I am 230 and 5'7. I do have a thick build and leg muscles and big breasts. Most my weight is in my abdomen. I want so bad to be pregnant but worries my weight is just gonna spiral out of control. I am other wise healthy. Perfect blood pressure and Heart rate and no other problems just self Imags issues. My OB/GYN said I am good to go on having a baby. Anyone else have similar situations?
