As : As doctors, the first thing we do when we hear that a 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 and a doctor's test can tell around when you should be getting your next period. Taking a test a few days after your period was supposed to start should make it fairly accurate. You may just want to take a second just to make sure. 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 continue to have an irregular cycle, you should give your doctor or your ob/gyne a call. Good luck!
