I really feel for you, being warded at 32 weeks with contractions must be so scary, and worrying about your baby girl on top of that is a lot to carry. Please trust your gynae team completely right now and do not try to manage the UTI on your own outside of what they have prescribed, as this one truly needs proper medical treatment to protect both you and your girl. If at any point your contractions pick up again or anything feels off, please go back to A&E or call your ward immediately, okay?
