I got a call from my ob today that I have a uti and they’re just now calling me when I was there 4 weeks ago.. should I be worried? Don’t google uti cause omg..

They did give me a 5 day antibiotic I need to pick up and start tomorrow. Has anyone has a uti or one while pregnant. Are they serious? Sorry if I sound dumb this is my second pregnancy and I never have had a uti ever.
