You are able to become pregnant throughout your fertile years, that is to say, from the time when you start to have menstrual periods until you reach an age when your periods stop (usually your late 40s).
The time between the beginning of one menstrual period and the next is called the menstrual cycle. It lasts about 28 days. In the middle of the menstrual cycle one of the ovaries releases an egg into a Fallopian tube- this is called ovulation. The egg moves down the Fallopian tube towards the womb.
The egg will then either be: 1. Fertilised by one sperm (conception)-
For the egg to be fertilised, it must encounter a sperm in the Fallopian tube. When you have sex, your partner releases millions of sperm into your vagina; some of the sperm travel up through the womb into the Fallopian tubes. If there is an egg in the Fallopian tube, one sperm will fertilise it. The fertilised egg will move towards the womb, become implanted in the lining and start growing into a baby.
Discarded with the lining of the womb (menstrual period).
If the egg does not encounter a sperm in the Fallopian tube and is not fertilised, it will be discarded with the lining of the womb at the end of the menstrual cycle and you will have a period.
It is important to know that a released egg can live for up to 2 days and sperm can live for up to 5 days within a woman's body; so if you have unprotected sex up to 5 days before ovulation or a few days after it you may become pregnant.
