Anyone test positive for group b strep at any point in their pregnancy?

I’m 14 weeks, and a urine sample just showed I have some growth of group b strep- much to my surprise, as I’m not showing any symptoms. My doctor has decided not to treat with antibiotics, since I will be receiving them before delivery… but I’m concerned. From what I’m reading, any bacterial culture growth should be treated during pregnancy, especially GBS. While the risks are low, they are not 0% for miscarriage in late pregnancy :/ Definitely not feeling good, looking for other experiences. I plan to get a second medical opinion this week.
