My period is seven days late

Pregnancy test: There are many factors that can affect your period. I recommend that you first take a pregnancy test if you are sexually active. Afterwards please see your doctor for a thorough check up.

Abnormal cycle: If your were sexually active 3 weeks ago you could be pregnant. If not, you are young and young women frequently have irregular periods. If you have no more symptoms, just wait a couple of months and it should come back to normal

Take the test: When used properly, modern pregnancy tests are very accurate and can detect pregnancy as early as the first day after a missed period. Anovulatory cycles, stress, weight loss, medication, exercise, and other benign things can cause menstrual irregularity.

Are you pregnant? : It only takes about 7 to 10 days for a pregnancy test to show up. If your test is positive then you are pregnant. If not and your irregular periods continue then you will need to schedule a visit for irregular periods.
