Hey There. Sunday Afternoon Around 5PM My Girlfriend And I

Hey there. Sunday afternoon around 5PM my girlfriend and I had unprotected sex and I ejaculated inside of her. We went to the drugstore and purchased plan b, which she took at around 6PM. The next 24 hours she felt very sick to her stomach and yesterday she had lots of cramps, nausea, dizzyness and some hormonal symptons (hunger cravings, etc). Last night she threw up a little bit as well. Today is the third day since we had unprotected sex, which I understand is when ovulation can occur. What am I looking at her, Doc?
