How soon can I do a pregnancy test after I have had sex?
Not all pregnancy tests work the same – some can detect a pregnancy after a missed period and some can detect it before a missed period. Read the packaging of the pregnancy test you get.
Pregnancy doesn’t start from the day a couple has sex. It can take up to seven days for the sperm and egg to fertilise and up to another eight days or more for the fertilised egg to bury itself in the lining of a womb. This is when pregnancy begins.
