Firstly have you waited for you next period to come. This is a big clue to weather or not you could be pregnant.
But what you are explaining doesn't really indicate that you could be pregnant, and most properly the urine sample would of picked this up, there is always the possibility that it wasn't picked up at the time.
I would recommend you go to your doctors as soon as possible, to find you just what is wrong with you.
Good Luck.

they wouldnt of checked your urine for pregnancy,it would have been checked for water infection,so take a test now

You know what you should do just to make sure is to take a pregnancy test! that is the only way you will find out

illness can present itself in so many ways. whether you're ill or pregnant, you can only find out with a visit to your doctor. pregnancy can easily be checked by using over the counter pregnancy kits which are pretty accurate.

a fuller breast usually indicates pregnancy, though. mine manifested as ulcer-like, with its feeling of nausea. i almost had an X-ray, thinking that it was ulcer. good thing someone told me that i might be pregnant so i had a pregnancy test first and voila! i was indeed pregnant.

no they would not have checked for that -- they are not allowed to "check" for other things unless noted -- u cud be pregnant -- go to a clinic and get the test -- or do it urself with the test u get at the drug store -- always use protection

it could easily be stretch marks caused by weight gain. Get a pregnancy test though!
