the only time i felt discriminated was when I was told we couldnt have DD1 at the private hospital here unless i wanted a CS!!! the labour beds where only rated to 120kgs!! that was the reason I was given. I hovered around the 120 mark with DD1.
But I had no problems at all once i moved over to the public and even though with DD2 i was lighter I chose to go public because I'd had such a good experience with DD1.
Try not to let your fears overshadow your excitement
