Thanks for the query.
You once consult gynecologist, get examined to rule out the leakage of amniotic fluid
and early onset of labor.
After ruling out them go for urine culture and sensitivity.
Then depending on the result you can go for antibiotic treatment.
Take plenty of oral fluids that will help in decreasing the infection.
