Hi there...I can understand your concern. But it is difficult to with this little information, if she can get
pregnant. Detailed history like, her menstrual cycles regularity, when was her last menstrual bleeding and when is the next expected cycle, will have to looked into. If it's been 1 week since the intercourse or she has missed her cycle,, ask her to take a urine
pregnancy test and consult a obstetrician for further evaluation.
