reply to Carrie Ann; I have not had a period in over 6mos; I have been tested for absolutely every thing. According to my Dr. chances are if everything else checks out you probably aren't ovulating, so your chances of getting pregnant are lower. But don't use it as a method of birth control. You may want to go on the pill if you don't want to get pregnant. At least you'll get a period regularily and that's a lot healthier. Good Luck!
