Yeh theres a chance. Seems you havent heard of or have forgotten about pre-ejaculation. Its wise to get her checked dude Peace
There is a chance, but it is a small one in the large scope of things. If she wants to test, wait at least 12 days after you humped otherwise you'll get a negative result using most DIY preggor tests. If she is preg youre fucking unlucky because the odds are very much against it. But don't make a habit on it. She should also get on the pill if she tolerates it. Condoms can break you know.
The sperm from the night before would have died by then as long as no fresh semen dribbled out of your dick before you put the condom on you should be fine
If you continue to put your wee-wee in your girlfriend without wearing a condom you had better be prepared to either accept the responsibilities of parenthood or accept the responsibility of killing the fetus. Even a minute or two is running too high a risk. Don't do it!
Doubtful. extremely doubtful - semen can not live in space or outside for very long under those conditions
Its not about what was on the outside of his penis guys. You can get pregnant from "pre-ejaculate." ie pre-cum.
