I weighed 224lb when I got pregnant with my 1st and the pregnancy was absolutely fine even though I was very tired. I put on exactly 22 lbs, which I lost almost immediately after my daughter was born. I did breastfeed though... My problem was that once I stopped breastfeeding I still ate the same way and ended up weighing 230lbs.
Worked hard to lose some weight but still weighed 203lbs when I got pregnant with my 2nd. Put on 27lbs but if it weren't for the baby kicking and the bump I would have not told you I was pregnant, I had loads of energy and worked until almost the day before my son was born.
Also breastfed and lost all the pregnancy weight even though I was eating large chuncks of cake everyday. I have stopped breastfeeding for almost two months now and have managed to control my eating and exercise and have started losing some more weight.
Neither pregnancy I worried about weight gain...
Good luck with the pregnancy!
