It depends if the boy can ejaculate and the girl has started her started periods.
Excellent.
after the mences. day betwen 14 to 19.............
There's a 25-75 chance favoring that you would not get her pregnant. You could use a condom and not get her pregnant, or you don't use a condom and you have a chance at getting her pregnant.
the chances are not that high due to the fact that your doing it before your period because most are more fertile 6 days after her period. But the possibiltes are the same.
If you have been on birth control for over a month then you are protected against pregnancy.
20 percent without condom
I am assuming that 'wrapper' is slang for condom, and yes, it is still possible to get pregnant with a condom, though it does reduce the chances.
Condom are considered to be 90% to 97% effective (depending on who you talk to). So even with proper condom use you have a 3% to 10% chance of getting pregnant. Most sources favor the 97% figure.
Well, condoms are effective 99% of the time, so... 1% chance.
Condoms are a good source of contraception if you use them properly, and they do not tear/break. If the condom didn't tear/break then, even if they did ejaculate inside you, there is very little chance you would get pregnant.
Very strong. Any penis-vagina contact without use of a condom can lead to pregnancy, regardless of ejaculation. Sperm are present in the fluid preceding semen. Always, always, always use a condom. If he won't, dump him. He's not worth it.
it could be likely some sperm entered you because sperm does swim. a hole in the condom any were is a likely posibility sperm entered you. but i would see a ob to be sure you are or aren't pregnant
