Obese and Expecting

Kellen • Pregnant with baby #1 after months of TTC and large weight loss. Hubby and I couldn't be more excited!
A week ago I found out that I'm pregnant (5w2d) with baby #1 after several months of TTC! Over the past year I had lost 90lbs getting ready for pregnancy. I'm still nowhere near my goal weight. I weighed 275 when I conceived and jumped back up to 283 with bloat. My doctor has given me the ok to lose weight while pregnant, at a safe pace of course. 
Mostly I was just wondering about the other mothers out there who were pregnant while obese or overweight. What are some difficulties you had? Any complications? Share your story!
