Is it possible that yeast infections cause late or missed periods?
No, yeast infections will not cause late or absent
Your periods are controlled by your menstrual cycle, hormonal changes between your brain and reproductive organs, they are not changed by a yeast infection in your vagina/vulva. Your vagina naturally contains yeast, if yeast could delay menstruation it would always be an issue, a yeast infection just means increased yeast growth. Your period is late for another reason like stress or ill-health, although if sexually active you may want to take a pregnancy test.
Yes, any kind of infection in the body can throw your cycle off causing it to come earlier or later, but, if you've missed it all together and are sexually active, you might try a home pregnancy test:)
