You can use the Ovy Pregnancy Test starting already 5 days before your period is due. There are 2 test strips in the box. The test is 99.9% reliable within just 5 minutes, comparable to a rapid test by your doctor. It detects the pregnancy hormone hCG (human chorionic gonadotropin) in urine above a concentration of 10 mIU/ml. It is simple and can be used at any time of day. You must hold the test stick directly into the urine stream or in the collected urine in the cup for 10 seconds. The test result is easy to read, as the result is clearly displayed on a strip. The next period is then automatically calculated using the accompanying Ovy App. All test results can be recorded in the Ovy App in order to start "Pregnancy" mode.
