AZO for UTI affecting fertility monitor results?

Kristin • Momma & Wife
So I was thinking today would be my peak ovulation day, but my fertility monitor says I'm still in high fertility. I've had a UTI for a couple days and have been taking AZO pills and an antibiotic. Can this affect my results or am I just not at peak yet? This is my first month with the fertility monitor so I'm not sure what will and won't affect it.
