A urinary tract infection in pregnancy has little effect. Because urinary tract infection is mainly inflammation in the urinary tract, while pregnancy is mainly the growth of a fetus in the uterus. When there is inflammation in the urinary tract, there will be frequent, urgent and painful urination, and urinary tract infection will affect the quality of daily life of pregnant women when it occurs, but urinary tract infection usually does not cause infection in the uterus of the fetus through local infection or blood infection. It is recommended that after the occurrence of urinary tract infection, do not be too tight, drink more water, urinate more often and pay attention to the hygiene of the perineum and urethra to prevent the infection from worsening. If the inflammation is heavy you can take oral anti-inflammatory drugs of the cephalosporin class, which will soon achieve a cure.
