Emergency contraception can and often does delay the menstrual cycle due to the large surge in hormones. It is 95% effective against pregnancy if taken with 24 hours of sex. There is no date you can expect it. When delayed by EC, it can take up to a month to get your period.
However, since your period was due on Jan 18th and you had sex on the 30th, it's a good idea to take a pregnancy test to rule it out. A test would be accurate by now. If negative, it may be another week or two before your period comes, due to taking emergency contraception. Take a test now, to rule out pregnancy.
