Hello Thanks for writing to us with your health concern. Generally, fingering cannot result in a pregnancy. Also, pre ejaculatory fluid can lead to pregnancy at times, however you have not mentioned if any penetrative vaginal sex occurred. If there was no vaginal penetration, then pregnancy cannot occur. However, you have already asked her to take Unwanted 72. When taken within 120 hours of unprotected sex, it is more than 80 % effective in guarding against a pregnancy. What started on the same day of taking the pill, is most probably not her normal period, however, it is more likely to be a withdrawal bleeding due to the hormones contained in the unwanted 72 emergency contraceptive pill. Also, this pill would affect her normal cycle. The expected period can be preponed or postponed for almost a week. So there is no way to predict the next date of her period. To be on the safer side, if you think there was some vaginal penetration, please take a pregnancy test 4 weeks after unprotected sex. All the best Take care.
