There : There is always a possibility you could be pregnant and there's no way to know whether you are pregnant or not without a test. It would be unlikely for vyvanse (lisdexamfetamine) to affect your menstrual cycle. As doctors, the first thing we do when we hear a young, fertile woman is having a light or 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. 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 poly cystic ovarian syndrome. If you continue to not have your period or if they become irregular, you should contact your doctor. You may also want to call your doctor to discuss various methods of birth control to find one that will work best for you. Good luck!
