As . As you are having yellow vaginal discharge and cramping, you need a pelvic exam to rule out infection. As you are concerned about pregnancy please take a test, and if you don't get your period in 2-3 days retake the test. But because of your cramping and discharge you do need an evaluation. If you develop pain, fever, or vomiting, then you would need to be seen as an emergency.
