Almost 34 weeks with twins.TMI?

hey everyone. I am almost 34 weeks with twin boys. I have had a great pregnancy, no complications. I have been put on moderate bed rest just because Im swelling really bad at night and the doctor just told me to take it easy for the remainder of my pregnancy. Well I do alot of laundry, clean the boys room religiously, and just relax. I have been drinking atleast 6 bottles of water a day, ontop of blue powerade( for some reason ive been wanting blue powerade the past few weeks) Well today, I noticed that my pee smelt very strong, it has never been really strong,and it was still very light colored. So I know im not dehydrated. Is this something i should call my doc about?? Has this happened to anyone else?
