Ovulation Prediction Kits (OPKs) and False Positives Having sex now should be at the top of your to-do list if you want to get pregnant. Once you get your first positive test result, you will ovulate in 24 to 36 hours. The surge triggers the ovary to release an egg aka ovulating. Before ovulation, your hormones change, and there is a surge of luteinizing hormone. What Does A Positive Ovulation Test Mean?Ī positive ovulation test means that your body has a higher level of LH than usual. For pregnancy tests, if there is a second line, no matter how dark, it is a positive result. The color of the test line has to be the same color or darker than the control line for a positive result. Ovulation test differs from pregnancy tests. The less expensive ovulation tests rely on you comparing the color of the test line and the control line. They are more expensive, but you will have a definitive yes or no answer. If you want to remove the guesswork, digital ovulation predictor kits are your best bet. Reading an ovulation test can be a bit tricky. Ovulation predictor tests detect the surge and let you know ovulation is near. Luteinizing hormone (LH) is the hormone that initiates ovulation by causing the egg to separate from the ovarian surface. Just before ovulation, a dramatic hormonal change takes place called the LH Surge. Ovulation is the process of an ovary releasing an egg from the follicle and allowing the egg to float down the fallopian tubes.
