Very rare...
IF a guy has been inside you with his penis, there is ALWAYS a chance of you becoming pregnant. However, blood will not make you pregnant. If a guy is bleeding inside you, then there is something wrong with his genitalia and both you and he should go and see a Doctor as he may have a disease which he can pass on to you.
If he had any pre-come or semen on him at the time, then yes, there is always a chance that you could get pregnant. If not, then i doubt you could get pregnant. Be careful of any sexually transmitted diseases though! =)
Take the morning after pill
yes
If a guy comes inside the girl, she can get pregnant no matter what, except if they are using contraception [condoms, etc.]
No, it means that you did not get pregnant that time. People do not get pregnant every time they have sex, but they can still get pregnant later.
Yes, seconds is enough.
not if you douche with bleach really fast
It is certainly possible, but not anywhere as likely as if he had ejaculated.
It only takes once with unprotected sex to become pregnant.
The order of orgasm has no bearing on whether or not you can get pregnant. Orgasm of either partner is not a requirement to become pregnant.
