The best time to take a pregnancy test is when you are most likely to get a positive result. This will be several days after ovulation, which typically occurs on day 14 of your menstrual cycle. Another good time is immediately after sex or within 48 hours of sex if you think it’s possible that conception occurred in this window of time. If your period hasn’t started yet and the signs point toward a successful pregnancy, it’s still not too late! You can do another test in two weeks to confirm that there really was an egg released from one of your ovaries during the last month.
