There are now home pregnancy tests that can confirm pregnancy a week before you miss your period.  That means that just 7 days after ovulation occurs and conception begins, you may see a VERY FAINT pink line.  But for those of us that overanalyze everything, we need to know even earlier. 1 in 4 pregnancies naturally ends in miscarriage.  There are also pregnancies called “Chemical Pregnancies,” which means that an egg and sperm may have met and tried to create a healthy fertilization, but something didn’t follow through.  A chemical pregnancy is the term given when a faint positive test result shows prior to a missed period, but then the cycle begins within a few days of when it was due.  The tests never grow darker and the hormones balance out quickly because they never rose above a very low amount.
