Hello, Pregnancy is a remote possibility when there is no ovulation, i.e., during the safe period. Moreover, since you used a condom, the safety is enhanced. Yet, if she is in the fertile or ovulation period, you can ask her to take an emergency pill or go for the insertion of an IUD, which can serve both as emergency as well as long-term measure. If none of these can be done, you should either get a blood test for pregnancy at least ten days after the intercourse or wait for her next normal period and go for further help if she misses it. Please remember that period may get delayed when emergency pill is taken. Hope this helps.
