You may have a urinary tract infection (UTI), a common disease. A bacterium that enters the urinary tract is one of the causes of such an infection. The sensation of burning and itching after urinating is a typical symptom of a UTI. You must drink plenty of water rather than holding in the urine. If the urge to pee occurs immediately, don't wait until you are comfortable. In addition, you should better put on cotton underwear and abstain from perfumed soaps in that area. If the symptoms do not improve, or become worse, it is necessary to see a doctor to run some tests and probably take some medicine to clear off the infection.

It is scientifically possible to have short phases during the first months of pregnancy. But it is vital to seek consultation from a gynecologist and do a pregnancy test to ensure that you are indeed pregnant.
