Lush Bath Bombs 💣🛀🏽

So I just got a bath bomb for Easter and I took a bath with it tonight!  Idk the name of it but it smelled of lemons and there was blue color inside of it!  I posted a picture of it exploding on Instagram and my friend commented "don't get a uti." I have never had a uti before and idk how you would get one from this bath bomb? Am I safe or should I have taken certain precautions before taking the bath? Kinda concerned bc I don't want a uti 😞 Thanks for the help!
