How soon after having sex can you take a home pregnancy test?
I take it you mean, how soon after having sex would the pregnancy test be able to tell you if you have conceived. The best thing would be to wait two weeks after you miss your period. But some of the new tests are touting that they can tell you 10 days after conception. But, if you don’t want to worry about false negative readings, and end up having to buy two tests instead of one, it is best to wait until two weeks past when you should have started.
