You have to miss a full period before taking a test. Your fertility is between days 12-19 on a 28 day cycle. Sperm will live in the uterus for as long as 5 days, so if you ovulate on day 14 and had sex on day 11 you can get pregnant. Keeping a calendar of your cycle will help you. Day 1 is the first day of your period and continues until the start of your next period. When you have missed I or more periods then you take a test.
