Mom bought me culturelle probiotics? Lol

Vee💃 • First pregnancy 😘 EDD: Nov. 1, 2015 😁👪❤️
It says promotes better digestive health plus supports immune system. I'm 25weeks+2days and on cephalexin for a UTI. I'm on my last two days and already have yeast symptoms 😪 doctor told me to take monistat 3 and that probiotics were safe. But have they worked for anyone??
