In brief: Possible

Ella (ulipristal acetate) is an emergency contraceptive that can be used as much as 5 days after unprotected intercourse.
It delays ovulation giving sperm time to die. This also means a delay in your period. That may be why your period is late. However, it, like all emergency contraceptives, is not 100% effective. To know for sure, do a pregnancy test and, if it is negative, repeat it in 3-5 days. Hope this helps.
