I'm 25 weeks and I am starting what I believe to be my 6th or 7th UTI since becoming pregnant. I only got antibiotics for the last 2. I have an appointment Monday morning so I'll ask about this again but what could be the cause of this? I've never had this problem like this. Any suggestions on how to prevent them better? I drink mostly water (lots of it), I'm hygienic down there, and I'm not sure how else to prevent it.
