The best time to take a pregnancy test is usually several days after ovulation, when the lining of the uterus begins to thicken. A positive result does not always mean you are pregnant; it can also indicate that your partner’s sperm has fertilized an egg inside you. Most women will get a positive result within two weeks of ovulation, but some may need longer to detect pregnancy than others. Some tests only offer ‘day-of service’, so it is important that your doctor or pharmacist advises you about this before testing. If there is any doubt about whether or not conception took place, then couples should wait until three weeks past their last menstrual period (LMP) before testing to confirm pregnancy.
