Pull and pray does not work to prevent pregnancy. If you had your penis in her without a condom, you risked getting her pregnant. You emit small amounts of sperm when having sex before the big ejaculation. Implantation hardly ever really happens in real life. If she is 9 days late, she should take a home test. But do note that women are often late and for a variety of reasons such as stress, illness, weight gain or loss, changes in routine, etc. So, she really could just be late. But you need to use a condom EVERY time to prevent pregnancy. good luck
