Taking Deviry (medroxyprogesterone acetate) will not affect the results of a urine pregnancy test. Pregnancy tests work by detecting a hormone called hCG, which is only produced during pregnancy. Because Deviry is a progestin hormone and does not contain hCG, it will not cause a false positive or a false negative result. You can trust the accuracy of the test. If you are experiencing missed periods or other symptoms, it is always best to consult your doctor for personalized guidance.
