As : As doctors, the first thing we do when we hear that a young, fertile woman is having a missed period or abnormal spotting, we check a pregnancy test. You can either take a home pregnancy test as long as it has been 5- 6 weeks since your last normal period, or you can go see your doctor and they can test you. A home pregnancy test is 97% accurate if taken a week or more after the missed period. Depending on when you took your home tests, it may have been too early for an accurate reading. A blood test can tell if you are pregnant as soon as 7 days after conception and a doctor's urine pregnancy test can tell if you are pregnant around when you next period should come. There are other reasons besides pregnancy that can cause a woman to miss a period such as: stress, diet, excessive exercise or a hormone imbalance such as with a thyroid disorder or polycystic ovarian syndrome. If you are not pregnant and are still worried about an irregular cycle, give your doctor a call. Your doctor will take a thorough history and physical and may run some tests to find out why your period is irregular. This is especially important if you are trying to become pregnant since problems that effect your period also effect your fertility. Good luck!
