Recurring uti advice

Hey so I’m currently 29 weeks & this is my third uti in my pregnancy , never had one before my pregnancy but it’s been happening probably after 20 weeks & I drink water everyday , I’m not sexually active .. I just don’t really understand why I keep getting these infections & I’m scared it will harm my baby , just last week I had BV so I took the antibiotics which I just got done taking just to find out I have a uti 🤦🏽‍♀️ so now I have to take ANOTHER round of pills for a week 😭😭 , any advice how to stop this from coming back & natural ways for this to go away ? thank you very much
