Chances she is pregnant from precum after urination?

I'm 19. I have read nearly all the articles regarding precum and pregnancy 1)I had not masturbated or ejaculated almost 3 days before she came over. (Didn't even ejaculate that night) 2)I DID urinate several times before the time. 3)I showered before. 4)I shaved. 5)I wiped off my pre before I put it in 6)This happened 2 weeks ago and she claims she is close to having her period. 7.)Her last period either started on Jan. 4th or right before. We did this on Jan. 17th I inserted my penis into my girlfriend’s vigina, wiped off precum then did it two more times while wiping off. I was basically in her for 5-7 seconds. then I decided to rather not do this. I don’t want to play around with my life, or create one.
