It's it's gone untreated yes, I'm 24+4 and I have a uti for the second time since I've gotten pregnant.
Agree with ash by time I got to the hospital my cervix had already started to soften 2 bags of fluid and antibiotics with a script for 10 days
Yes it can cause premature labour etc - go get antibiotics (if its really really bad they'll hospitalise you on iv meds)
I went into labour @22weeks on my first bby because uti's.
If gone untreated it could have negative effects on your pregnancy.
I have bladder infection and it sent me into preterm labor was in l&d for 5 hours before contraction finally stopped
For now no but you need to take care of it before birth
