My penis is not circumcise;masturbated in the morning;didt wash;andhad sex at 11pm;will the leftover semen around glans beable to get my gf pregnant?

Hard to guess: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (when conception might have occurred), or 1 week after missing a period. Nobody knows for sure how many sperm survive in said foreskin circumstances.
