Pregnant or am i just stressing it?

i was having sex with my girlfriend with the withdrawal method.
as im doing it,i kept on pull out my penis and check if thr's (pre-cum)
as i see,my tip of my penis is dry.
on that day,in the morning my girlfriend helped me with ha****b thn 4 hrs ltr we had sex and i did urined before we do.
also i did nt put my penis all the way in as she is too tight,for a moment i felt that im havin pre-cum.
so i quickly pull out and rub it on her leg.
it took about 10mins i did nt cum at all.
in the end i finger her and we stop.
bt nw we r so paranoid about pregnancy...im so stress and so regret i did nt use a condom...
i need some help to tell me is thr goin to be pregnancy?
i need answer quickly...im insanely stressed up...and worried for my girlfriend. thanks!
