They are lower than if you did not use one but no form of contrception, with the possible exception of abstinence, is foolproof.
Excellent.
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.
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.
after the mences. day betwen 14 to 19.............
It depends if the boy can ejaculate and the girl has started her started periods.
If you have been on birth control for over a month then you are protected against pregnancy.
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.
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
Condoms have a 3% failure rate if used correctly.So chances are very small if used correctly.
