Ob-Gyn questions? Ask a gynecologist online.
Hi and thanks for your question.
There is a probability that you are testing too early, if you ovulated late in your cycle you would get positive test after two to three weeks. As you mentioned you have graves disease and on medication, that might be the cause for your delayed period because menstrual irregularities are quite common with thyroid problems. First is you should rule out pregnancy by testing again after a week.
Let me know if you have further questions.
