What are the chances to get girl pregnant if i was inside her for only one minute and did not feel to cum at all?

Still possible: You shouldn't do this as men produce small drops of semen early during sexual stimulation and each drop has about 20 million sperm per drop.

Not zero: Women get pregnant under the weirdest circumstances. That is why gynecologists consider every woman pregnant, unless proven otherwise.

Low but not zero: Any time an erect penis is in a vagina, there is a chance of pregnancy. The risk of pregnancy is much lower if you didn't ejaculate but it isn't zero. Best wishes!

Impossible guess: The odds are low, about 10-15%. My advice would be to reduce your chances to almost 1-2 % and avoid dying young, use a condom regularly
