Pregnancy related

Patient: Hi My age is 21 and my gf is 20 years old.I recently masturbated and then after 30minutes i touched my gf vagina.We both are virgins.And im sure there was no liquid in my hand as my hand felt dry (not wet or sticky).Is there any chance of her to get pregnant? I am worried..please help.Her periods came last week only so will come back next month.Unless i get a response i am not able to sleep.should i ask her to have ipill..just in case?

Doctor:
