plus size and TTC?

Any women on here over 250+ pounds and conceived? Any health complications, anything different you had to do, is it hard to find maternity? Spare the lecture on loosing weight for a healthy pregnancy...I'm working on it but it's hard. I've lost 40+ pounds in the last 3 months but still having these concerns and questions about this stuff. 
If you don't mind sharing what was your weight before pregnancy, during and after? Could you actually tell you were pregnant like in pictures?
