Can't be "normal"

Ammi
My feet, legs and hands are swollen like this from a month and I am 38 weeks now .. It has started to develop rash (sometimes itching) and hurt so bad all the time. All my joints are hurting now. Last time I met my OB he said its normal and there's no protein in my urine sample so he's not worried but I can't 
 xplain how painful and uncomfortable it's getting day by day.
