I have a yeast infection for the first time (at least I think so based on symptoms - very itchy, different smell than usual). Last night I started using the Monistat suppository & cream. This morning & just a few minutes ago, I noticed that there were a lot of bubbles in the toilet after I peed, almost like my urine is frothy. Is that normal? It doesn't hurt to pee, nor is it an unusual color. Thanks!
