A little more time: Typically you should wait at least 7 days after you have missed your cycle before taking a pregnancy test. There are many different reasons like stress, medication changes, etc that can cause your cycle to be off by a few days. If you miss an entire cycle, and the pregnancy test is still negative, you should make an appointment to be seen by a gynecologist.
