Sorry to butt in, but it would be far too early to take a pregnancy test. Even if sperm did reach an egg, (which is possible, but quite rare at this point in your cycle) it takes a few days for it to implant and even then a couple of weeks for the hormone levels to increase to a level that would be detected by the off-the-shelf pregnancy tests. Even the First Response ones which say that you can test before your period is due requires a reasonable level of hormones, which would not be present at this early stage. You’re going to have to wait another couple of weeks before any pregnancy test to give you a correct result.
