The Pregmate ovulation test strips are easy to use – just dip one in a cup of your urine for a few seconds, lay it down flat and wait 5 minutes for the results. The strips are sensitive enough to detect even low levels of the luteinizing hormone (LH), which spikes just before ovulation. Not only are these ovulation tests great for those trying to conceive, but they can also help you avoid pregnancy if you're not ready. By tracking your ovulation cycle, you'll know exactly when you should try to conceive or use extra precautions, depending on your personal plans.
