If i missed my period by 2 days and i have white discharge what does that mean?

Late period?: It sounds like you got your period, but that it was 2 days late. It sounds like you also have white discharge. The white discharge might or might not be yeast. If it is yeast, it would likely be accompanied by itching or burning. Yeast also occurs most often after taking antibiotics or in a diabetic.

Could be infection: Do a pregnancy test to see if you are pregnant. See your doctor to see if you have an infection.
