Hi there...I can understand your concern. Now there's pretty much nothing you can do. If you haven't ejaculate inside her, then there's very little chance that she will be
pregnant. She will have to wait for her menstrual cycles to come on 26th. If she misses then she can consult a obstetrician for further evaluation. Also she can take a urine
pregnancy test at home in another 5 days to check for pregnancy. If positive consult a obstetrician.
