What are the chances of pregnancy if I did not penetrate but I did pre ejaculate she stopped having her period 9 days ago and she is a virgin thanks?

Don't know... It's possible. It can happen - and that's what matters. Use latex condoms to protect your partner from pre-ejaculatory fluid. I have seen pregnancies in women who had no penetration whatsoever. Since you are intimate, it's time to see your doctor or go to planned parenthood to get some birth control advice. Why chance it? Life is stressful enough! good luck. Lgromkomd.
If pre-ejaculate was. deposited at introitus there is a very small chance. Most studies have shown low levels of sperm or no sperm in pre-ejaculate with sperm not being motile (however, don't know how promptly samples were examined). One small study published in 2011 showed that there are some individuals with a high motile sperm count in pre-ejaculate. See: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3564677/
