Thanks for the query,
if you have touched your pre-ejaculate which is known to contain live sperms and then have inserted the finger into her vagina, then there are all chances that she may get pregnant. It is suggested that if pregnancy is not desired then she should opt for emergency contraceptive pill within 72 hrs.
I hope I have answered your query in detail,
Wishing you good health,
