3 year old girl UTI

My daughter was fine yesterday today she’s crying when she pees saying it hurts she had two accidents very rare for her.. I took her to urgent care she peed for them and it came back that she has a uti

I’m so sad seeing her in pain but no fever and she’s eating/ drinking good but when she pees it breaks my heart hearing her cry…

We got antibiotics that she started today. Any tips on how I can make her more comfortable? My anxiety is so high I read people getting the wrong antibiotics and it not working and it worries me soo much
