Yeast infection as a symptom?

I was on antibiotics 2 weeks ago for a UTI, I know with antibiotics usually comes a yeast infection. I do find it odd I would get it this much later after the antibiotics, but anything is possible. But I did notice in the phamplet that comes with monistat, it says pregnancy can cause yeast infections from all the hormonal changes. Has this been a symptom for anyone? Last week it did feel like AF was coming bc I was super emotional but now it doesn't feel like AF is coming. I don't really want to look too much into everything but I don't have my normal PMS symptoms.
