I had my tip in my gf and scared of precum getting her pregnant.i felt my penis tighten a few times as when your going to cum soon.chance of pregnancy?

1 in 5 risk...: "Pulling out" decreases risk of pregnancy some; however, sperm are secreted prior to ejaculation (even with no tightening). Your chance of pregnancy from this one incident is low: < 2%. If you continue to have sex, your risk increases to 20% over the course of the year. Encourage her to get on the pill, implant, shot or other more effective method unless you want to become a father!
