Sneaking in from 2nd tri - I was 5'4" and 290 lbs when I got my BFP. I have lost weight/not gained anythign so far at 19 weeks. Baby is perfectly healthy. Not sure if any of my complications (sickness, aches and pains, etc) are a result of being overweight, but it definitely made me nervous! Next time around I'd like to lose some weight and see how different it is.
