There : There are other reasons besides pregnancy that can cause a woman to miss a period or ahve an irregular cycle such as: stress, diet, excessive exercise or a hormone imbalance such as with a thyroid disorder or polycystic ovarian syndrome. Also, if you are currently on a birth control method such as Depo Provera (medroxyprogesterone) or an iud, you can also have an irregular cycle. If you continue to have an irregular cycle, you should give your doctor or your ob/gyne a call. Good luck!
