Fertilisation can only occur when there is a viable egg in the uterus. An egg is released when a woman ovulates, typically around day 14 of her cycle (day 1 being the first day of her period). There is then a "window" of time when the egg is both viable (i.e. possible to fertilize) and in the right place that it could implant in the uterus. This window is usually about 2 to 3 days.
<i>However</I>, a man's sperm can survive in the vagina for a suprisingly long time, which means that fertilisation could occur up to several days after you actually had sex, so that even though you had sex before your fertile "window", you could still become pregnant.
It is important that you take this on board in the right way. It is all too easy to imagine that if there is only a window in any given month when you could get pregnant that it's not that likely that you'd get pregnant from one unprotected incidient, or that if you avoid the middle of your cycle and your "window" then there's no way you could get pregnant. Sadly, this isn't true. The figure of day 14 is an average, and your fertile window may be before or after then: there is no time in your cycle when you can have safe unprotected sex unless you know for certain when you have ovulated (which involves tracking the temperature and mucus levels in your vagina).
To summarise, because I know it's a bit sciency: yes, it is true that there is only a comparitively small section of your cycle in which you can pregnant. It is false however to assume that because of this it's safe to have sex at any point in your cycle. All the best. [ hailebop's advice column | Ask hailebop A Question ]

A girl can get pregnet anytime after she has had her first period.If she wants want to get pregnet though its best to try at the end of her cycle when her eggs r fresh and ready to be fertalized.HOPE THAT HELPS :) [ --LISA--'s advice column | Ask --LISA-- A Question ]
sbloemeke answered Monday September 12 2005, 9:15 pm: One day out of her cycle. And no, that is not always true, as there are sometimes when something weird may happen.
Yet, even if she does get pregnant, 1 in 4 conceptions are miscarriages. [ sbloemeke's advice column | Ask sbloemeke A Question ]

xomegaroni answered Monday September 12 2005, 8:16 pm: definately not true. not sure where you heard that, but there's certain days of your cycle that girls can have a better chance of getting pregnant. maybe thats what you mean. if you have any other questions, go to-
MFS answered Monday September 12 2005, 8:12 pm: No, that is not true at all. While you ovulate only for a brief moment - the egg that is released is viable for fertilization for a few days. Add to that the fact that sperm can continue to live for as many as 4 days and you have a situation where pregnancy can occur over a rather broad range of days.
