Thanks for posting your query.
If you are not having any symptoms of urine infection like burning during passing urine, going frequently to the toilet or pain in the lower abdomen or fever
, it is okay not to take antibiotics. Drink lots of fluids, which can help flush out the infection. However, if you have any symptoms like these, see your doctor, who may want to repeat the urine test and also do a culture and sensitivity, to see which bacteria is causing the infection and which antibiotic could get rid of it. Some antibiotics are quite safe in pregnancy
. So, if needed, you could take one, prescribed by your doctor.
