I had it once in my 20's and again in my 30's-- I'm prone to bladder infections, and I kept getting them again and again for months one year- and never had any other symptoms (that I could tell)- and the doc checked me for BV and that was it- just a big dose of antibiotics. No real symptoms in my 30's either-- not even bladder infections. Just discovered it when I went in for my annual after my LO was born. Again, dose of antibiotics- for 10days- no worse than normal biotics (least for me).
Obviously depends on you- but if you suspect it could be, better to get it checked out hun.
