I have all the symptoms of early pregnancy but i went to the er and they said i have a uti and vomiting and nausea , but it doesn't burn when i pee bu?

Yes. A uti can mimic: A urinary tract infection can cause the symptoms you are experiencing. Pregnancy can put you at risk for utis because It can lower your immune system. If you don't have a menses after a week, I would retake a urine pregnancy test. It can take time for the pregnancy hormone hcg to build up to detectable levels on a pregnancy test.
